A new study demonstrates that specific traits that distinguish humans from their closest living relatives — chimpanzees, with whom we share 96 percent of our DNA — can be attributed to the loss of chunks of DNA that control when and where certain genes are turned on.
Seeking specific genetic changes that might be responsible for the evolution of uniquely human traits, Howard Hughes Medical Institute investigator David Kingsley and colleagues at Stanford University scanned the human genome for features that set us apart from other mammals.
Only about 4% of our genes differ from that of chimps, and the team found that this represents 510 segments of something or other between us and our hairy cousins.
BUT! This is where is gets interesting kids!
Careful analysis of a handful of these segments demonstrated that loss of regulatory DNA could explain how humans developed some features not found in other animals — such as big brains — as well as how they lost features common in other species, such as sensory whiskers and large spiny penises.
You know what this means for us guys. right?
We traded in ‘cats whiskers,’ and a large spiny penis for a big head!
So!
The next time some asshole brags to you about the size of his dick……………………………., just point to your forehead and smile!
