A Male and Female human

"Your species is a brutal and destructive one. And less significant in the universe, than a single bacteria, on a coral reef.
Maybe, but we have one thing you appear to have lost on your evolution to disembodied know-it-all. We may be frayed at the edges, but we still have love. And while we have that, we still have hope.

Humans or Homo Sapiens (Latin for "Wise Man") are the only hominid species alive upon the planet Earth. It is believed that. Homo sapiens sapiens (Modern Humans) originated in Africa around 200,000 years ago.

Humans have a highly developed brain, capable of abstract reasoning, language, introspection, and problem solving. This mental capability, combined with an erect body carriage that frees the hands for manipulating objects, has allowed humans to make far greater use of tools than any other living species on Earth. Other higher-level thought processes of humans, such as self-awareness, rationality, and sapience, are considered to be defining features of what constitutes a "person".
