Biology - January 2007

In Darwin's time there was a relative lack of evidence supporting his theory, but he still found a considerable amount in fields like biogeography, embryology, and paleontology. Now, advances in science have added new evidence in those fields, as well genetics, microbiology, immunology, and a host of others.

Evolutionary principles have lead to better treatments for diseases such as leukemia and AIDS, and speciation has been witnessed in scientific experiments involving short-generation species such as fruit flies. Also, fossils of "transitional species" such as tiktaalik continue to emerge as predicted.

Thus far, opponents to evolution have focused vainly on undermining the research without providing a reasonable alternative.

So why is it that 51% of Americans don't accept evolution? If we're really still in such a Dark Age-mentality, why don't we also still believe that the world is flat, that the sun revolves around it, and that literate women should be burned at the stake?

My biology teacher stated that since there is an enormous amount of co2 going into the sea, within fifty years all the fish in the water will die thus causing starvation around the world. Can this be true?

I want to know why animals and people are so different in intelegence. There are many animals with bigger brains, and humans (Cro-magnons, homosapians) haven't been here that long (1 million years.) compaired to many other animals like sharks or bugs who have been here for about 100 million years. Will we grow too strong and destroy the world somehow and seal the fate of our existance?

My husband thinks that because identical twins have different finger prints then they don't have identicle DNA. I thought that identical twins were the same egg and same sperm but later the egg splits into two after being fertillised. This would make the twins have exactly the same DNA wouldn't it? Every finger has a different print on it, I mean your 8 fingers and thumbs would have different prints.

I'm taking a biology class this semester. We've touched on evolution here and there. Today, we talked about origins of life. I've heard the argument of certain elements combining to create amino acids which can lead to life forms. The professor said that the new supported theory is that life actually came from a meteor or something in outer space. That just seems a little more far fetched to me. Amino acids make sense, and, considering the process has been duplicated in a lab, makes me wonder why people are suddenly supporting the new sci-fi-esque theory. What do you think about both? What do you think is more likely?

I don't want any creation answers here. If you have something to say about evolution being a lie or creation being the only way or some such, please redirect your attention somewhere else. I'm not interested.
