Title: The giant squid once faced a population bottleneck Written by: duddy on Mar 21, 2013 (https://biology-forums.com/gallery/47/4_21_03_13_12_21_25.jpeg) (https://biology-forums.com/index.php?action=gallery;sa=view;id=11475) Genetic testing of giant squid corpses discovered all over the world has found that not only are they all the same species, they have surprisingly low genetic diversity. This suggests that some time in the recent past they were pushed to the brink of extinction, but managed to rebound and are now found throughout the worlds oceans. |
