Human ancestor species

There are three generally accepted categories of human ancestor species:

Wave 1 were propagated from Terra/Sol by the {roach} Race

Wave 2 were propagated by the lizard and bat races from Terra/Sol

Wave 2b were propagated by the various races from discovered wave 1 populations

Crossbreeding with Wave 2 species and hundreds of thousands of years of localised evolutionary adaptations have made these distinctions primarily of acedemic interest

Wave 1
Based on archaeological records these species included Homo Ergaster, Homo Erectus and two still disputed species - the Homo Gautengensis population of {planet/star} and the Homo Habilis population of {planet/star}

Wave 2
Based on archaeological records these species included Homo Heidelbergensis, Homo Neanderthalensis, Homo Cepranensis and Homo Rhodesiensis.

Many individual finds dated to very early in the Wave 2 period also contain Homo Erectus or Homo Gautengensis genetic traces leading to disputes as to whether these populations are properly classed as Wave 2B or whether the the contamination existed in the source population in the same way as varying degrees of homo neanderthalensis contamination can be found in homo sapien terranis.

Wave 2B
This classification is usually reserved for populations that chronologically date to the Wave 2 period but consist of a Wave 1 species already having significant adaptation to their transplanted environment.

The difference between wave 2 and 2B is primarily of academic importance when accounting for otherwise inexplicable genetic traits such as the recessive {feature} of the population of {planet/star}
