The Impact of Glacial Cycles on Biodiversity
The main process that has shaped biodiversity throughout much of the world is the glacial cycles. These ice ages, which started around 2.5 million years ago, have had a significant impact on biodiversity by causing species ranges to expand and contract. Studying deep time paleogenomes can help researchers understand how these glacial cycles have influenced biodiversity over time.
