"The word human can refer to all members of the Homo genus, although in common usage it generally just refers to Homo sapiens, the only extant species. The name "Homo sapiens" means 'wise man' or 'knowledgeable man'."
Sorry I looked at your meme and interpreted it using the common useage of the word "human", instead of interpreting it from the context of evolutionary biology. my bad for thinking you were using it in it's common sense, because you posted it alongside a meme. humans in the common sense have existed for roughly 300,000 years. humans in the "homo genus" sense have existed for millions.
maybe next time specify that you are using a very niche interpretation of the word "human" next time so troglodytes like me don't misunderstand your very well researched lexicon
cry some more about it
