Nature lovers have unwittingly been acting as data collectors, especially people that create lists of wildlife they see at home, in the park, or during a hike. Birdwatchers are known for […]
How six elements came together to form life on Earth
How did life begin?

Let us now praise human population genetics
Exactly who are we anyway? Over the last generation, population genetics has emerged as a science that has made the discovery of human origins, relatedness, and diversity knowable in a way that is simple not possible from studying texts, genealogies, or archeological remains. Viewed as the successor to a race science that promoted the superiority of some human groups over others and that provided a basis for prejudice, forced sterilization, and even extermination, population genetics is framed as a discipline that is based on discovery using the amazing content of fully sequenced human genomes and novel computational methods.
