At least our genes are. The Nature website reports that establishing the age of each mutation in contemporary human populations is important to fully understand our evolutionary history and will help to us to develop new medicines for diseases caused by genes.
Many of these mutations have only recently arisen--approximately 73% of all of them (and 86% of the ones that cause disease) have arisen in the past 5,000-10,000 years, which sounds like a long time, but is a blink of an eye in evolutionary terms.
Also, people of European American ancestry have an excess of these harmful gene variants compared to African Americans, due to the Out-of-Africa dispersal of homo sapiens millions of years ago.
Here's an idea: Could some of us have a genetic propensity to encounter the Visitors? That would make them a sort of hybrid species (NOTE: Subscribers can get this wonderful hardcover for LESS than $5!)
