Evolution #10

Evolution is the process of growth or development.  There is also two different types of evolution, microevolution and macroevolution.  Microevolution has to do with the changes within a species.  Macroevolution is when a species changes into another species.  There are many reasons to support evolution but there are many reasons to say that evolution never did happen.  I believe that it didn't occur ever.  There are so many gaps in the fossil findings and so many questions it makes it hard to believe.  There are also different people saying different things and not agreeing which makes it hard to think its real.  I do not believe that we evolved from apes and I think that is all crazy talk.

Evolution #9

A cladogram shows evolutionary relationships based on physical features.  Many of the cladograms show that humans branch off from chimps and the closest ancestors are the Australopeticenes and the homo erectus and the cro. mag.  According to our cladogram features that seemed more apelike was bipedilism, flat foreheads, and canine diastema.  Some say that we have been evolving in the past 200,000 years and some say we have not been evolving.  Personally I do not think we have been evolving but there are many reasons to support both sides.
