One interpretation of the genetic evidence is that the split of the Neanderthal lineage from the modern human lineage occurred between 440,000 and 270,000 years ago.<span>
It was a long time ago that our ancestors, the Neanderthals, lived on this planet. It was also a long time ago that we started moving away from them and developing in a new manner that would almost completely sever the ties that connected us to them.

This is an example of developmental homology. Studying embryological development of living things provides clues to the evolution of present-day organisms. During some stages of development, organisms exhibit ancestral features in whole or incomplete form. Homologous structures are those structures whose underlying similarity arises from their being derived from a common ancestral origin while analogous structure are those whose similarity comes from their performing of a similar function.
