Uncovering Ardipithecus Ramidus

Uncovering Ardipithecus Ramidus

Kristopher Jordan Krohn

8 million years ago a tremendous even occurred; a new branch of primates split off from the chimpanzee family tree, creating the first hominid. At least, that is the current accept theory of how the first hominid came to be, but without physical evidence to support this claim it cannot be set in stone. When first discovered Ardipithecus Ramidus was thought to be the last common ancestor between chimps and humans. With recent analysis of the femur, skull, teeth, and other long bones this speculation has been disproven, but so much more information has been gained about the human ancestor. Ardipithecus Ramidus is an amazing find because of the techniques used to excavate the fossil, the way the species walked, ate, the shape of the skull, and sexual dimorphism….
