July 10, 2023 Research shows global cooling of the climate 10 million years ago led to an explosion of diversity in terrestrial ...
Oct. 14, 2022 Vertebrate genomes are repositories for retrovirus code that was deposited into germ line as inherited endogenous retroviruses during evolution. Researchers now provide new findings about retroviral ...
Sep. 2, 2021 The rise and fall of Earth's land surface over the last three million years shaped the evolution of birds and mammals, a new study has found, with new species evolving at higher rates where the ...
Mar. 21, 2022 Biologists have developed a new method to measure the extent to which regional geographic features -- including barriers between regions, like mountains or water -- affect local rates of speciation, ...
May 13, 2021 A new approach to genomic species delineation could impact policy and lend clarity to legislation for designating a species as endangered or at risk. Evolutionary biologists model the process of ...
Dec. 19, 2022 Diving birds like penguins, puffins and cormorants may be more prone to extinction than non-diving birds, according to a new study. The authors suggest this is because they are highly specialized and ...
Mar. 29, 2021 Research into the flower preferences of pollinating moths may have delivered a vital clue to the simple factors needed for the emergence of new ...
Aug. 19, 2021 The common weed known as white clover releases toxic cyanide when its leaf tissues are damaged. This chemical defense, a response called cyanogenesis, helps it to deter insect pests. Research shows ...
Apr. 7, 2021 While studying genetic diversity in bumblebees in the Rocky Mountains, USA, researchers discovered a new species. They named it Bombus ...
Sep. 28, 2021 Using a new mechanistic model of evolution on Earth, researchers can now better explain why the rainforests of Africa are home to fewer species than the tropical forests of South America and ...
