99.4% of the most critical DNA in humans is identical to chimps
I did find this fact to be surprising. I am not used to studying this kind of information so I had no idea. I find it interesting that our DNA is so close yet our appearance and ways of communication are so different. Yes we might have some similar appearance characteristics but I feel there is a lot more difference then .6%.

Blog on today's class
I was interested in the article about placing stem cells in knees to help regenerate cartilage. Cartilage is on of the hardest things to regenerate because of lack of blood flow. Lots of money has gone into research to find a sufficient replacement for cartilage but no solution has been reached yet. Knee injuries are a big problem for many athletes. But not just athletes, people who love working out or just people that inherited bad knees. I think this sounds like it is having some success. I am interested to see what future outcomes are. I think placing some stem cells in a knee is a lot less invasive then getting a knee replacement. The reason for knee replacements is because all the cartilage is worn down and a person has bone on bone contact. This seems like a good solution to me if it can keep on having results.

Biology Week 2
Evo-Devo
Evo-Devo is a biology that compares the developmental processes of different organisms to see the ancestral relationship between them and see how this development evolved. So it starts back at the origin of the ancestor and then sees the process of development the organism goes through. I think think this is cool to look at to see how and why organisms develop into different things. There are many factors that go into an the development of an organism. I think one of the main things that causes change in development is ones environment.
How does Darwinism matter to me?
Charles Darwin developed the biological theory of natural selection. Natural selection is a theory where all small species of organisms develop through the natural selection of small, inherited traits that increase the individuals ability to compete, survive and reproduce. I do not know how this really matters to me but I think Darwin makes a very good case. It is survival of the fittest. The individuals that inherit the traits that help them survive longer will outlive the individuals that inherit weaker traits. Thus, this species will survive longer and these stronger traits will continue to reproduce.
