- Some four billion years ago, when cellular life emerged, a typical primordial microbe likely had only a small set of genes. Today, however, genes abound. We, for example, have 20,000 genes that encode proteins. Dogs have their own set, and so do starfish and fireflies and willow trees and every other species on Earth.

Oct 8, 2014 · A man who died in 315 BC in southern Africa is the closest relative yet known to humanity's common female ancestor – mitochondrial Eve.
Sep 13, 2023 · Even more impressive, the geneticists concluded that all human beings on Earth right now can trace their lineage back to the Eve gene, a single common female ancestor whom scientists called the Mitochondrial Eve. She lived around 200,000 years ago.
Dec 16, 2023 · Did Red Hair Come From Neanderthals? A common urban myth states that red hair in humans comes from Neanderthals. Humans in today’s world generally have mutations on the melanocortin (MC1R) gene that causes an over-production of pheomelanin, which produces a red hair color.

Aug 26, 2021 · In this episode we’re taking a trip back in time, soaking in the primordial soup to discover the origins of DNA, find out where genes come from and how some species have stolen theirs from viruses, and explore what’s next for the genetic code.
Jul 11, 2024 · The new results come after more than a decade of effort to find fossilized bones and a second genome of a Denisovan, the mysterious archaic human discovered through its DNA 14 years ago. That first Denisovan genome came from a girl’s pinkie finger bone dated between 60,000 to 80,000 years ago.
