SCIENCE IS SO COOL LIKE
"We are like dwarfs sitting on the shoulders of giants. We see more, and things that are more distant, than they did, not because our sight is superior or because we are taller than they, but because they raise us up, and by their great stature add to ours."

This tumblr's for all the great men and women of science for whom we owe our current understanding of the natural world; their achievements, their failures, and even their quirks, we celebrate them all.

For Science. For Inquiry. For Humanity.

A genetic migration map of the Y-chromosome in humans, divided into haplogroups i.e. groups linked by last common ancestor with a single nucleotide polymorphism (SNP) mutation.
Much like with the Mitochondrial Eve and human matrilines, human genetics proposes that there is a theoretical last common ancestor from whom all living humans are patrilineally descended from: the Y-chromosomal Adam.
Current studies suggest that Y-chromosomal Adam (or Adams) lived as early 60,000 years ago, around the time of the Out of Africa Migration and tens of thousands of years after Mitochondrial Eve.
