Step 1: Look at article I posted. Find first reference:
Tennessen, J. et al. 2012. Evolution and Functional Impact of Rare Coding Variation from Deep Sequencing of Human Exomes. Science. 337 (6090): 64-69
Step 2: “Copy” the reference into your browser.
Step 3: Open Google Scholar
Step 4: Paste the reference into Google Scholar.

Another article to which Science refers comes to a similar conclusion because:
The development of agriculture and livestock in the transition from the Paleolithic to the Neolithic era some 10,000 years ago heralded a demographic explosion in our species that is still ongoing today. Paradoxically, this rapid population growth, made possible by improved living conditions, may be responsible for an excess of damaging variants in our genome
In other words, as humans developed agriculture and animal husbandry they became more diverse.
Sorry, but your first post said "The original work appeared in "Science" magazine". The author, Jeffery Tomkins, does not appear in Science, the article that he used to draw his conclusions does. The other article that I referenced above speaks of the transition from Paleolithic to Neolithic over 10,000 years ago. Does this mean that the young Earth theory is wrong or can we just skip this background foundation because it goes back too far?
Sorry, but cherry picking articles to find evidence that you want while ignoring others that do not fit your conclusions is dishonest.
