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.
