Creationism vs. Evolution

Ever since I was a little girl I have been brought up with the explanation that God made us according to his image. Because I was a little girl I just went along with what my parents and my teachers from church used to tell me. Now I can totally say that I believe in creationism because I choose to. Evolution is many theories scientist have made in accordance to how humans came to be. To me evolution is just theories that scientist come up with to explain their curiosities. As told in the bible God made this world in 6 days(Exodus 31:17) and then made man kind. I believe that there is such great power as God. I believe that with a blow he gave us the sense of breath. I do agree with natural selection, that is why I think that we are capable of adapting to our surroundings and that is why there is such diversity in the way people look and behave. But I just can't seem to comprehend how we supposedly evolved from a molecule or that chimps evolved into what we know today as human race. Evolution brings many questions to mind when I think about it. Like, If we did evolve from chimps what happened to all the fur or hair they had? Where did language come from? Why are chimps now in days not evolving anymore? To me it is much easier to believe in Creationism than evolution. Never in a world with such perfect order can it direct itself from the nothing without a powerful being to control everything that moves throughout the planet Earth and that is God. This is my point of view and I strongly believe in it because that is how it is stated in the bible.

Creationism v. Evolution

Creationism is the theory of a greater being creating all forms of life. while evolutionism argues that life started from one cell and changed over a long period of time into the species and breeds we have to day. although there are some aspects of evolutionism that make sense, i am a believer in creationism.
certain aspects of evolution i do agree with, such as Natural selection and adaptation. Once god created earth in 7 days i do believe that natural selection played a role in which species are able to survive. Adaptation also affects whether species survive in the world.
There are several examples that support evolutionism, but they either have gaps or just don't make sense. for example saying that everybody comes from a cell and "evolved" in to the very complex systems we are. This is hard to believe that a single cell could copy itself and change its self various times to get the numerous different cells in the human body. Creationism to me is the only thing that makes enough sense to believe.

My View

I'm against evolution, but not adaptation. I've looked in both aspects and there are to many questions in evolution that aren't answered. All of evolution is based on theory's and probablity's which aren't really founded.
With the man's experiment proving that things can arise from nonliving things should not be the basis of all evolution.What is the probaibly that all the circumstance aligned perfectly together to form a living organism? Even in the bible god says we were made from dust and you can see when we die are body does what?.
There is so much evidence in my life that there is a god that i don't believe we orginated from chimps. Science is based on reasoning and since they couldn't reason god great power in creating the world in 7 days they proclaimed it impossible. God said human wisdom is foolish and can't comprehend his ways.
There are so many statements and experiments that are for evolution, but so many miracles and phenomonens in life that counter act that and show that there is a higher power in life.
With adaption i believe animals do evolve and change sameway people have done. God created man and woman, one of each, and look how much variations there are. Since God is big and vast so are his creations. People are made in the image of God and who said God is one image or face? There are to many if's with science that i can't stand for evolution. If people believe in withcraft, evil, satan, and ect. why isn't there a God.
Science is soly on human reasoning and I don't rely solely on human thinking since it can be corrupt(can be seen in our own way of thinking). There is a higher power and people believe in other things in what that higher power is, but there is one.Our bodies are to complex to have been made by just a passing of time.
(I will put a video later on)

Test for yourselves by opening both books the biology and the bible.

Assignment -- Creation vs. Evolution Post -- Posted by Mrs. Berkeley

The theory of evolution is one unifying principle of biology. However, evolution has also become one of the most controversial topics over the past 150 years since the publication of The origin of species by Charles Darwin in 1859. The teaching of evolution in the American school biology curriculum has been repeatedly challenged by groups and individuals who believe in the special creation of organisms (creationists; "scientific creationism"). More recently there has been a revival of the "creation by intelligent design" viewpoint.

In this assignment you are to briefly define the two viewpoints. After providing brief introductory information, support one side of the evolution vs. creation debate. In your response be sure to provide explations supporting your conviction. After your initial post, you are to reply to two other posts on the blog. This assignment is not intended to create divisions amongst your peers, but instead is intended to motivate you to think critically and be able to set forth conflicting points of view. Please be respectful and reasonable in your posts. Worth 30 points. Due Wednesday, March 12, 2008.

Adapted from: http://www.millsaps.edu/religion/creationandevolution.shtml

evolution is fact

I believe that Creationism is for religion and evolution is science. Creationism fills the gaps of the theory of evolution. It can be proven that living things can evolve to fit their living requirements.So can't that be a base for evolution to be proven?

video that supports evolution



A chemist named Stanley Miller proves that life can be created from nothing. In his experiment called origin of life. This shows the creation of life from nothing.




Fossil evidence supports the origins of life on earth earlier than 3.5 billion years ago. The North Pole fossils from Australia are such that even more primitive cells must have existed earlier. From rocks of the Ishua Super Group in Greenland come possibly the earliest cells, 3.8 (?) billion years ago. J. William Schopf of UCLA recently discovered possibly photosynthetic prokaryotes from North America in 3.5 billion year old rocks, suggesting the existence of even older heterotrophic forms. The oldest known rocks on earth are 3.96 billion years old, and are from Arctic Canada. Thus, life appears to have begun soon after the cooling of the earth and formation of the atmosphere and oceans.

These ancient fossils occur in marine rocks, such as limestones and sandstones, that formed in ancient oceans. The organisms living today that are most similar to ancient life forms are the archaebacteria. This group is today restricted to marginal environments. Recent discoveries of bacteria at mid-ocean ridges add yet another possible origin for life: at these mid-ocean ridges where heat and molten rock rise to the earth's surface.

This is the proof of evolution.

Creationism makes sense DAH !!!!!!!!

I am a great believer of creationism because the whole idea of evolution seems illogical and creationism gives the human mind answers. First of all I want to say that this is my opinion only, I am not trying to criticize anyone’s believe or anything but I do believe that everyone should be presented with the information and it should be left on him/her to decide what to believe.
Evolutionists beleive that the universe, with all that it contains (space, time, matter and energy), exploded from nothing. This is opposite to the First Law of Thermodynamics. Where did space, time, matter and energy come from in the first place? So the ultimate question of origins of species remains unsolved for Evolutionists because the first law of thermodynamics state that energy can’t be created nor destroyed. So wait, if energy can’t be created then how did universe come into existence in the first place? Ahh perhaps creationism is the answer that God is almighty who has control of everything created the universe out of nothing. That’s 1 for creationism and 0 for evolutionism because evolutionism failed to explain how the origin of universe came into existence but creationism explained it clearly that god created it out of nothing. Second BIG problem with evolution is that how can Living things come from non living things. Ok, to back this argument up lets just take DNA for example, all living things have DNA or any living thing that is dead has DNA and non living things don’t have DNA. So using this FACT how can we say that we evolved from non living things when non living things never had DNA and living things need DNA. So that’s 2 for creationism and 0 for Evolution because living things evolving from non living things don’t make sense and there’s a huge proof against it that its impossible but a human brain can grasp an idea that a creator or GOD created living things out of nothing, I mean science disagrees with this but then again the theory that science comes up with is rubbish because it goes against human sense and scientific evidence. Furthermore, before we discuss the whole idea that did humans evolve from chimps or not, lets talk about how could new genetic information arise? Evolutionists believe that all life evolved from a single cell, so for that to take place a lot of new genetic info would have to be added to the cell, so where would all those genes come from? So where did all these circulatory system, immune system, urinary system, intestines and so on systems come from when they were not found in the original ancestral species. See it just doesn’t make sense. That’s 3 for creationism and 0 for evolution because creationism explains it that’s Gods almighty and he has total power so he created Humans or other living species as themselves out of his power. So far evolution doesn’t make sense because it doesn’t explain origin of life and living things evolving from non living things is just absurd. But creationism gives the human mind something to grasp on that logic can explain that the universe is the creation and it was created by the creator or God. Furthermore The theory of evolution teaches that simple life forms evolved into more complex life forms such as fish, amphibians, reptiles, birds, and mammals. There is no natural law known that could allow this to happen. The best that evolutionists can come up with to try to explain how this might have happened is to propose that it happened by mutations and natural selection. But mutations and natural selection do not show gain in information, just rearrangement or loss of what is already there. These are just some of the reasons why creationism makes sense and evolution seems absurd. Stay tuned for the next part of the issue to get enlightened because on the next issue I answer the question of the century that are we descendants of chimps?

Comment on Philip's Blog

I really enjoyed your post and even though i didn't read it before the test, it would have probably helped me during the test. You pretty much said all the important aspects of the chapter but there was some key terms such as fertilization which you failed to mention. However everything else made crystal clear sense. In addition the diagram on Meiosis really made sense and helped me memorize and comprehend the steps. I had a better understand the differences between Meiosis and Mitosis. I also understand how meiosis can have anaphase 1 and anaphase 2, telophase 1 and 2 etc,even though i could used it for the test. I Also like how you put a great emphasis on Crossing Over, because it is a important part of meiosis. The videos that you posted, even though they were hard to find, i still enjoyed them because it told me a lot about meiosis and mitosis without me reading so much information. Chow, Chow, Chow, Chow!!!!!!!!!!!!!!

comment on philip's blog

Philip, everything you wrote seemed very helpful to me especially the little hints you would give about where on the test certain things would appear. It got me looking at almost everything the same way and if you posted somthing about fertilization and meiosis in plants and fungi and a comparison of mitosis and meiosis i think your blog would have been solid. But, the only regret i had after reading your blog was that i didn't read it sooner because i truly believe it would have helped me on the test. Hopefully your next blog would be just as good if not better.

comment on Philipos Blog



i would like to comment on Philip's blog about how cross over takes places. he was right about how it takes places, but could have gone more in depth about it.

Crossing over takes places in prophase 1 of meiosis 1. Chromosomal crossover is the
process by which two homologous chromosomes exchange portions of DNA. Crossover usually occurs when portions of homologous chromosomes brake off and rejoin with other chromosomes. This is the exchange of genes, which is called genetic recombination.

comment on CHAPTER 13

chapter 13
philip i liked the your post about meiosis and mitosis and the stages they go through. meiosis and mitsosis has much more then these process. you should've mentioned somethign about crossoverin detail for example it's a exchange of genetic material between homologues that occurs in prohase1 of meiosis 1. And also you should've talk msomethign about the three types of life cycle which are animal, fungi and plant. and their functions are: plant: alternation of generation, diploid stage is called sporophyte in which spores produce plant and haploid stage is gametophyte in which gametes produce plants divide mitotically. You should've mentioned some information about Asexual and sexual reproduction. I think that's about it philip

comment on Philips Blog

Philip, your information was very good and helpful, but I just wanted to add a little something. Meiosis occurs in organisms that reproduce sexually. Sexual reproduction is when two parents give rise to offsprings that have unique ccombination of genes inherited from the two parents. The role that meiosis takes in sexual reproduction is that it combines sets of genes from two different parents, forming genetically diverse offspring. This takes place in the sex cells.

Comment on Philips post

Philip, your post was very understandable and made clear sense. It would have been very helpful if you posted somthing talking about fertilization and meiosis in plants and fungi and a comparison of mitosis and meiosis for the test. Overall, yours did help with the multiple choice. Thank you

Part II Meiosis


I am back again to now give everyone a quick summary on the second division of meiosis. This can also be called Gamete Formation. In prophase 2 the dna does not replicate, now entering metaphase 2, the chromosomes line up on the equator just like in the first divisional phase of meiosis. During Anaphase 2, the centromeres divide and each sister chromatid heads toward the opposite pole. Finally telophase 2 occurs and cell division is complete. Four haploid daughter cells now appear at the end of meiosis. Here is a picture that breaks down meiosis and that is the end of my post. Hopefully my post helped anyone in the class. New sherpa is Robert!

Part 1 of Meiosis

I am going to talk about some key parts of meiosis that everyone should know or hopefully will get a better understanding of after this discussion. Meiosis, a type of cell division, produces an egg and a sperm cell. Meiosis has two types of nuclear division. I will begin with interphase 1, though this starts before meiosis begins, the genetic material is duplicated/replicated. When the first division of meiosis begins, Prophase 1 will begin and this is where the chromatin condenses. Now, the most important part of Prophase 1 should start. The term is called CROSSING OVER. The meaning is as simple as the actual word. A exchange occurs between the two sister chromatids and the chromatids actually physically break off and then it is attached to a different homologous (same) chromosome. Everyone should know this term because most likely it will be on the test (probably short answer portion). Metaphase 1 now starts and this is when the homologous chromosomes line up in the equator (around the middle). Then the homologous pairs seperate but the sister chromatids stay together and this is called Anaphase 1. Last but not least, Telophase 1 begins and two daugther cells form. They have only one chromosome from the other homologous pair. I am not sure if this video will work on your computers but go ahead and try it but i would suggest watching it after i post part II of my discussion on meiosis. There are two websites, but i only will tell you one because the second one is right below it, hill.com/sites/0072437316/student_view0/chapter12/animations.html. Paste this into google and there will be search results, click the one that says Biology 201(about the fourth or fifth result). Once the page loads, scroll down and you should see in bright red letters Too See an animation on meiosis go to: The third and fourth URL, are the two vids i wanted to show you. The third has audio and once you click it (pick the one that says, stages of meiosis) and the fourth does't have audio but both are great videos. Also be aware, if you are watching these videos in the school library that Ms. Johnson will probably activate VISION CONTROL , and when you try to explain that it is for school, it is already too late.

10.25 chapter 9 review

Today we reviewed chapter 9, which was on cellular respiration.

So here are some quick notes for review.

Oxidation: lose electrons, release energy, exergonic.

Reduction: gain electrons, stores energy, endergonic.

The three stages of cellular respiration: glycolysis, citric acid cycle, oxidative phosphorylation.

~38 ATPs / 1 glucose

Two types of fermentation: alcohol and lactic acid.

To remember, just remind yourself that lactic acid fermentation is what we experienced when we did that painful bending exercise and alcohol fermentation is what we’ll be doing with the root beer experiment.

“I really don’t like your boyfriend, Glycolysis. He’s not producing enough ATP.”

10.24 Chapter 8 Review

So yesterday we reviewed chapter 8, which was an introduction to metabolism. Here are some quick notes you should remember.

-Metabolism includes all of the chemical reactions in an organism.

-Catabolic pathways breaks down more complex molecules to simpler ones.

-Anabolic pathways makes complex molecules from simpler ones.

----To remember anabolic pathways, I thinking of anabolic steroids helps me. They are steroids that build up the body’s muscle mass. Don’t ask me why I know that.

-The first law of thermodynamics states that energy can be transferred and transformed but cant be created nor destroyed.

-The second law of thermodynamics explains that energy transfer or transformation increases the entropy, disorder, of the universe.

-Exergonic reactions proceeds with a net release of free energy

-Endergonic reactions absorbs free energy from its surroundings.

-Energy can be kenetic or potential.

-Kenetic: energy of motion. Ex: light and heat

-Potential: energy of position. Ex: arrangement or location.

-If it ends in –ase its an enzyme.

-Enzymes have three different inhibitors: competitive, noncompetitive and feedback.

These images may be helpful in better understanding the different inhibitors.

AP Biology Lab 2: Enzyme catalysis

Kamran posted this entry

Hey class, this is the summary of todays lab and i hope you will understand the lab better after reading this blog entry.

Enzymes catalyze reactios by lowering the activation energy necessary for a reaction to occur.
The molecule that an enzyme acts on is called the substrate. In an enzymatic reaction, the substrate changes and becomes into products but the enzyme molecule is unchanged after the reaction and it can continue to catalyze reactions over and over again.

In part 2: Test of Catalase activity, the enzyme that was used was the catalase, the substrate was H2O2 and the products came out to be water and Oxygen. When the catalase was added to the H2O2 solution oxygen bubbles started to form because catalase is an enzyme which speeded the reaction.



Although in the next step the catalase was increased but it was boiled causing the enzyme to change its shape and it became denatured so nothing happened. There were no oxygen bubbles observed. Also, in the last step of this part of the experiment, when the chicken liver was added to the H2O2 huge amount of Oxygen was released because alot of oxygen bubbles appeared. Here is a similar video of chicken liver and H2O2 being mixed.


So, from this part of the experiment it could be concluded that the living tissue produced the most oxygen and it had the fastest reaction rate.

For part 3, the purpose of the lab was to investigate the rate at which the enzyme catalase converts substrate to product. The catalase reacted with H2O2 for various amount of tie and then it was stopped by adding the H2SO4. So the remaining H2O2 needed to be measured so a titration with KMNO4 took place. Here is an overall image of the experiment.





In the overall results it could be concluded that as time passed the number of moles of product also increased.
well, thats it, i hope u guys learned something and hopefully it wasn't that boring. Ok now for the moment everyone has been waiting for, the next sherpa who will have the honor of leading us is............... Aerialle.

Class 10/22/07

well...here goes nothing.

first this is a video on cellular respiration done by kids in a AP Bio class in Vermont i think...
http://youtube.com/watch?v=FFBr3ANCkb4

glycolysis not only breaks down glucose but can accept a wide range of molecules such as polysaccharides and other forms of 6C sugars(galactose and fructose). The diffrent molecules would then be changed and broken down into glucose, then the process is continued.

main facts about glycolysis
it breaks 6c glucose into 2 3C pyruvates
forms net of 2 atps
and 2 NADH

krebs cycle yields
1 atp
3NADH
and 1 FADH2

*remember numbers produce in krebs cycle is multiplied by 2 because there are TWO pyruvates each going through the cycle.

one glucose can produce 36-38 ATPs
