- Reposted by Bruce S. LiebermanYes, some people's legacies are complicated. For example, Watson. After all, though he was racist, don't forget his other traits. For example, he was also sexist. And also anti-semitic. And a data / idea thief. So let's not forget all the different facets.

- Reposted by Bruce S. LiebermanInteresting a lot of recent theory-focused papers I've been reading about fossils don't acknowledge the vast amount of paleobiological literature on the subject(s) they're discussing. I'm happy folks are excited about fossils but also confused why folks seemingly aren't reading papers about fossils

- Reposted by Bruce S. LiebermanFor hundreds of millions of years, marine annelids had remarkably stable genomes. Then, a sudden and drastic transformation occurred. In non-marine lineages like earthworms and leeches, the genome structure massively reorganized in a short evolutionary window.
