💥 We highlight the problem (elephant in the room) of using a single reference genome.

➡️ We put forth a set of hypotheses on how variable genomes contribute to adaptation and diversification

Scientists claim they’ve made ‘pivotal step’ in bringing back the dodo for first time in 300 years Thousands of dodos could return within a decade according to Colossal Biosciences, a ‘de-extinction’ company – but experts warn of ‘moral hazard’

“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?
