Out today in @currentbiology.bsky.social and led by @tillramm.bsky.social! We integrated population genomics, fossils, SDMs, and micro-CT scanning to understand how climate change has influenced extinctions and extant genetic diversity in the threatened Australian mountain dragon #ozherps #genomics
Climate change predicts Quaternary extinctions and extant genetic diversity in a threatened Australian lizard
Ramm et al. show that Quaternary climate change predicts local extinctions and intraspecific differences in genetic diversity of the threatened Mountain Dragon (Rankinia diemensis). Their data suggest...

How many chromosomes can an animal have?

In our paper out now in @currentbiology.bsky.social we show that the Atlas blue butterfly has 229 chromosome pairs- the highest in diploid Metazoa! These arose by rapid autosome fragmentation while sex chromosomes stayed intact.

Constraints on chromosome evolution revealed by the 229 chromosome pairs of the Atlas blue butterfly
The genome of the Atlas blue butterfly contains ten times more chromosomes than most butterflies, and more than any other known diploid animal. Wright et al. show that this extraordinary karyotype is ...

New findings in Science suggest that rodents owe much of their evolutionary success to their thumb-nail (the first digit, D1), an adaptation that gave them dexterous hands for cracking seeds and nuts.

Archaeologists once assumed that men were responsible for seafaring trade in Papua New Guinea. New research shows how women played a fundamental role.
