"No evidence of transposable element bursts in the Galápagos Scalesia adaptive radiation despite hybridization, diversification and ecological niche shifts"

No evidence of transposable element bursts in the Galápagos Scalesia adaptive radiation despite hybridization, diversification and ecological niche shifts - Mobile DNA
Transposable elements (TEs) have been hypothesized to play a pivotal role in driving diversification by facilitating the emergence of novel phenotypes and the accumulation of divergence between specie...

“Rich Grenyer, a biologist at the University of Oxford, said de-extinction is a “dangerous” distraction and that gene-edited animals are “at best a sort of simulation, rather like those unnerving animated AI portraits of dead relatives some… people create”.”

A while back (maybe 3-4 years?) there was a paper on common misconceptions of the genetics of various traits. One of them was eye colour in humans. I have lost this reference and can't find it anywhere. Does anyone recognise what I mean?

If you know anyone interested in starting a Master's project working on ammonoid phylogenetics (or the phylogenetics of a mollusc group spanning the OAE2 event in the Late Cretaceous), then ask them to get in touch with me.

The situation is a little tricky, as it would be funded by the remainder…
