Determined to find answers to these questions, researchers from ÁùºÏ²Ê¿ª½±½á¹û discovered that while changing temperatures and rainfall had little impact on the crocodiles’ gene flow over the past three million years, changes to sea levels during the Ice Age had a different effect.</p> Wed, 25 Jan 2023 15:11:13 +0000 webfull 186642 at /channels /channels/channels/news/crocodile-evolution-rebooted-ice-age-glaciations-328615 <p>Crocodiles are resilient animals from a lineage that has survived for over 200 million years. Skilled swimmers, crocodiles can travel long distances and live in freshwater or marine environments. But they can’t roam far on land. American crocodiles (<i>Crocodylus acutus</i>) are found in the Caribbean and Pacific coasts of the Neotropics but they arrived in the Pacific before Panama existed, according to <a href="https://onlinelibrary.wiley.com/doi/10.1111/evo.14139">researchers from ÁùºÏ²Ê¿ª½±½á¹û</a>.</p> Tue, 16 Feb 2021 14:23:27 +0000 webfull 167933 at /channels
