DPS Ammonite Posted May 10, 2019 Share Posted May 10, 2019 A rail species twice evolved into a flightless species on an island that then submerged and re-emerged. “The extremely rare process is known as iterative evolution -- the repeated evolution of a species from the same ancestor at different times in history.” https://www.cnn.com/2019/05/10/africa/white-throated-rail-extinction-scli-intl-scn/index.html The press release that references the original scientific paper: https://www.eurekalert.org/pub_releases/2019-05/uop-tbt050919.php Quote from above Eurekalert website: “Fossil evidence presented here is unique for rails, and epitomises the ability of these birds to successfully colonise isolated islands and evolve flightlessness on multiple occasions.” Link to abstract and paywalled journal article: https://academic.oup.com/zoolinnean/advance-article-abstract/doi/10.1093/zoolinnean/zlz018/5487031?redirectedFrom=fulltext See Wikipedia: https://en.m.wikipedia.org/wiki/White-throated_rail 1 My goal is to leave no stone or fossil unturned.

Auspex Posted May 13, 2019 Share Posted May 13, 2019 I assume that they are comparing skeletons? Pretty hard to separate King Rails and Clapper Rails on that basis... There must be an underlying genetic predisposition, carried in a surviving branch through the years and seeding convergent evolution when the environment was right. 2 "There has been an alarming increase in the number of things I know nothing about." - Ashleigh Ellwood Brilliant “Try to learn something about everything and everything about something.” - Thomas Henry Huxley >Paleontology is an evolving science. >May your wonders never cease!
