The origin of humans - Coursework Example Contrary to the argument, genes are not transferable to other species hence different species poses different appearance. There is a great confusion since appearance can be helpful in species identification, hence disregarding the biological definition (Lewin, 2005). The evolution of man contrasts the biological definition of species in the aspect of appearance. The successful interbreeding of Homo sapiens and Homo neanderthalensis biologically denotes them to belong to the same species biologically (Lewin, 2005). Neanderthals are closest relatives of Homo sapiens but belong to different species. Their evolutionary trace is in Asian and Europe while Homo sapiens fossils are in Africa. They concur in appearance but form different species hence more confusion when dating the human evolution. Strict biological definition concentrates on testing and stating theories for biodiversity measurement through taxonomy family levels. It has broad scale consideration but various implications. In consideration of species definition, it becomes difficult to assign the correct taxonomic rankings for the fossil study (Sober, 1994). The challenge is that, most living species interbreeding documentation is imperative since past fossils can no longer mate although the need for dating human evolution and origin is still
