May 26, 2022 — The raw material for evolution is much more abundant in wild animals than we previously believed, according to new ...
May 26, 2022 — For the first time since its discovery 130 years ago one of the most mysterious fossil vertebrates has finally been classified, increasing our possible understanding of the first animals to crawl on ...
May 23, 2022 — A comprehensive family tree, based on DNA sequences, has revealed that drywood termites have made at least 40 oceanic journeys over the last 50 million years to reach far flung ...
May 17, 2022 — Early animals formed complex ecological communities more than 550 million years ago, setting the evolutionary stage for the Cambrian explosion, according to a new ...
May 12, 2022 — From embryo to turtle cracker: Palaeobiologists studied the multiple changes in tooth shape in the tiger shark. The study is also central in drawing conclusions about extinct species from the myriad ...
May 12, 2022 — According to a new concept, it was a novel molecular species composed out of RNA and peptides that set in motion the evolution of life into more complex ...
May 12, 2022 — The genetic origins of the first agriculturalists in the Neolithic period long seemed to lie in the Near East. A new study shows that the first farmers actually represented a mixture of Ice Age ...
May 11, 2022 — Ancient moa DNA has provided insights into how species react to climate change, a new study has ...
May 4, 2022 — A significant change in the genetics of tiger sharks reveals a vulnerability to direct exploitation and shark control ...
May 4, 2022 — Squid, octopus, and cuttlefish -- even to scientists who study them -- are wonderfully weird creatures. Known as the soft-bodied or coleoid cephalopods, they have the largest nervous system of any ...
May 3, 2022 — New research moves back the moment of the radiation of squamates -- the group of reptiles that includes lizards, snakes and worm lizards -- to the Jurassic, a long time before current ...
May 2, 2022 — The absence of large herbivores after the extinction of the dinosaurs changed the evolution of plants. The 25 million years of large herbivore absence slowed down the evolution of new plant species. ...
May 2, 2022 — Study of Campanula americana supports strengthening conservation efforts in glacial refugia areas because of their high genetic diversity. Conservation of those areas in the southern Appalachians and ...
