Can humans reproduce asexually?
Humans cannot reproduce with just one parent; humans can only reproduce sexually. … These organisms can reproduce asexually, meaning the offspring (“children”) have a single parent and share the exact same genetic material as the parent. This is very different from reproduction in humans.

The oldest skeleton discovered of our species Homo sapiens (so far) is from Morocco and is about 300,000 years old.
Has a virgin birth ever happened in humans?
IN THE closest thing to a human virgin birth that modern science has ever recorded, British geneticists last week described the remarkable case of a young boy whose body is derived in part from an unfertilised egg. … Sometimes, an unfertilised mammalian egg will begin dividing, but this growth usually does not get far.
