New paper alert! We reconstructed the diversification trajectory of sharks & rays over the past 145 myrs to answer: When did they experience major extinction events? Does age play a role in extinction selectivity? If so, does it change with extinction intensity? 👉 doi.org/10.1098/rspb...

GWAS has been an incredible discovery tool for human genetics: it regularly identifies *causal* links from 1000s of SNPs to any given trait. But mechanistic interpretation is usually difficult. Our latest work on causal models for this is out yesterday: www.nature.com/articles/s41... A short🧵:

As I say here, this is not about saving the planet. The planet will be orbiting the sun long after we’re gone. The question is, will there be a healthy, thriving human society on that planet? The answer to that question is very much up for grabs at this point.
