Evolution and adaptation are frequently used interchangeably when describing trait change. Does it really matter?

Our new paper in PLOS Biology shows that yes, it really does. journals.plos.org/plosbiology/...

Very happy to see our paper out in Nature! 🦇🦇🦇🦇🦇

A huge collaborative effort to revisit the evolutionary history of bats using 103 reference-quality genomes and an extensive fossil dataset, and to build a genomic resource for many questions still to come.

Where did bats come from?🦇🌍

After decades of debate, the biggest bat genome + fossil study ever done has an answer - and it’s not where anyone expected!
