How do homo sapiens express themselves artistically?

Homo Neantherdanelses to Homo Sapiens, How do you explain this?

• Well, lol, forget about the heading i know how Homo Sapiens derived from other Homo Species, my question is actually different. Abiogenesis right? that created first life on earth? the single cell whatever life that is. 'first life' evolved to create multicellular organisms and thus plants animals bla bla. I want to know deriving from 'first life' on what stage it got divided into two genders of same species like man and woman in homo sapiens, or male cockroach and female cockroach or male bird and female bird. My question is "When did the phenomenon of 'two kinds of gender in the same species' appeared first?" "When did the two gender types first started to copulate to give birth to any of either types?" "Is there any evidence of existence of "three or more gender types in a Species (may or may not do sexual reproduction'?" Does my question bore you to death?

• Answer:

  Your own biology is confusing you - other organisms don't have to be like humans with distinctly different sexual organs and with two distinctly different sexes (in fact humans aren't as neat as all that either). Sex evolved many times in many ways leading to organisms with hundreds, even thousands of sexes without morphological differences - no sexual organs or several sets of sexual organs. Some sexual species have lost one of the sexes and still do just fine; others have evolved sexual reproduction, then lost it, and later re-evolved it. Like most of evolution, the evolution of sex is very messy without a single path followed by all species, and repeatedly using cellular components to do things for which they didn't evolve - they just happened to be around at the right time; much of it remains a mystery.
