Why Don't We Have More Fossils?

AdultsArchaeologyEvolutionGeology
When you see a bunch of fossils in a museum, you might not think about how unlikely it is that they got there. But there's a lot of lucky dice rolls that landed that mastodon in the museum, and researchers are really motivated to find out what factors influence any organism's odds of fossilizing. Here's what we know and what we need to know.

The ocean is evolving, and it’s not based on the ‘survival of the fittest’

AdultsEnvironmentEvolutionOcean

Another Ancestor Paradox

AdultsEvolutionGeneticsHistory

AdultsFamilyHumanSocietyEvolutionPsychology
Why do we love people we're related to? Compared to strangers, why do we feel such a deep sense of connection with our family members? Sure, they're nice to us, we take care of each other, and we often live with them, but there has to be a deeper biological reason. That reason, unsurprisingly is evolution. In this video, I explain why taking care of our family, or even dying for them, makes sense in the eyes of evolution.
