GENOME: Chromosome 2: Species

Until 1955, many people agreed that every human being had twenty-four pairs of chromosomes because in the year 1921, Teophilus Painter tried to count the unpaired chromosomes of a dead man's testicles and arrived at the number twenty-four. Other scientists repeated his experiment in different ways and agreed that the number was twenty-four. Apes have 24 chromosomes where as humans have 23 chromosomes. Human beings are "an ecological success". Human beings were apes , a group that went extinct fifteen million years ago. We have inhabited every inch possible on Earth and we are 98% confident, that "chimpanzees limits, human beings." We are more chimpanzee like than any other animal related to the chimpanzee is. Genes partially control our behavior. It is part of the reason why we do the things we do. Humans derived from a different and distinct species millions years ago, and through the process of evolution, we have become what we are today. Human beings.
