Selection
Paul Andersen explains the importance of selection in biology. Artificial selection occurs when humans choose traits that will be selected for or against. This has created the variety of domesticated animals and crops. He then describes...

Genetics - Lost and Found: Crash Course History of Science
Sometimes trail blazers of science aren't famous like Darwin or Pasteur. Sometimes they're humble Abbots, just growing peas in the back of their Abbey. This is the story of Gregor Mendel and how his work was done, lost, then found again.

Eugenics and Francis Galton: Crash Course History of Science
After Darwin blew the doors off the scientific community, a lot of people did some weird and unscientific stuff with his ideas. Francis Galton and a few others decided natural selection could be used to make the human race "better" and...

Earth Science: Crash Course History of Science
It's Earth Science time!!!! In this field, natural philosophers were asking questions like, what’s up with fossils? Are they the remains of extinct organisms? Or are they so-called “sports of nature”—rocks that just happen to look like...
