Human Evolution and the Fossil Record.
Scientists continue to debate the history of man.
It is generally agreed upon by the scientific community, however, that humans evolved from lesser beings, and this essay will function to provide evidence to support this claim. Several points will be outlined, including the general physical changes that occurred between several key species on the phylogeny of man, and a discussion of dating methods used to pinpoint the age of the fossils. This essay will begin with a brief discussion of dating techniques. This makes this method useful for dating of recent fossils, with good accuracy, up to 50,000 years back. It is the difference between this ratio now and the time is died that allows a date for it to be established.
