Our thinking about what it means to be a “species” is changing with every cool new insight (and this one is 👍🏼👍🏼 !). Taxonomy wants discrete boxes into which organisms can be placed. Nature denies us this simplicity.
Scientists have discovered a remarkable human who lived in Siberia 90,000 years ago. Her mother was a Neanderthal, and her father was a Denisovan. Here’s my

Super interesting phylogenetic analysis of SARS-CoV-2 origin. While it remains unknown whether the adaptations that made the virus so transmissible occurred in humans or an animal host, the virus is clearly a product of natural selection.

I am particularly sad about Luzia, the oldest human fossil found in Brazil. She lived in south-central Brazil some 12,000 years ago and was such an important historical artifact. I can't stand the fact that we lost her.

Don’t let this garbage get you down. The truth is not that women are bad mentors for women - I’m sure you’ll be a great mentor! The truth is that there are inequities in science that work against women. These are the barriers that we need to work to break down.
Extraordinary results require extraordinary proof. This has been the mantra of

Somebody on FB found a great supply of "paleontologist" stock photos and they're great but none of them are as perfect as this dude in a lab coat giving a sheep skull a flu shot
I miss going to conferences because being there meant freedom to focus on just that one thing. Virtual conferences mean doing that, and maybe another simultaneously, and also regular work and childcare, thank you time zones.
Today I finished recording the audiobook version of Life As We Made It, which is released in a month (Yay! Yikes!). Reading out loud for hours was was fun and exhausting… but now I’m freaking out about how my voice will sound on the audiobook. Is that normal? 😂

New Science paper argues horses came to the Americas earlier than previously thought—a conclusion that, if it holds up, rewrites the history of the N. American West. Strikingly, the article is from a team of archaeologists, geneticists, and Lakota researchers and elders. 1/15
Ok so Santa Cruz schools are closed? Ok. That’s the right epidemiological decision. Can handle this. Cool cool. What, my cuticles are bleeding? Weird. All good. Gotta get back to porting those UCSC classes to online. (Please be nice to each other out there. We’re all stressed.)
