DeepMind has created a genome atlas mapping the effects of approximately 9 billion human gene mutations. The article content failed to load due to technical issues.
A 2005 study by Dehal and Boore reconstructed evolutionary relationships across tunicate, fish, mouse, and human genomes to investigate whether vertebrate complexity arose from two ancient whole genome duplications. By analyzing paralogous genes duplicated before the fish-tetrapod split, they found clear patterns of four-way paralogous regions across the human genome, providing strong evidence for two distinct whole genome duplication events in early vertebrate evolution.
Potamopyrgus antipodarum, a tiny New Zealand snail, has undergone genome duplication, possessing three or four chromosome sets instead of the typical two. Whole-genome duplication is rare but evolutionarily significant when it stabilizes, occurring across plants, insects, and vertebrates. Recent advances in DNA sequencing are revealing polyploidy's prevalence and importance in driving evolutionary change.
