A team of researchers from across Europe and Israel has found evidence of dogs traveling with people from the Near East to Europe during the Neolithic. In their paper published in the journal Biology Letters, the group describes ...
The Tasmanian tiger was doomed long before humans began hunting the enigmatic marsupial, scientists said Tuesday, with DNA sequencing showing it was in poor genetic health for thousands of years before its extinction.

(Phys.org) —Increasing levels of carbon dioxide (CO2) in the atmosphere are causing oceans to become more acidic. This situation poses a threat to marine organisms with shells made of calcium carbonate, because acid will ...
(Phys.org) —At some point, scientists may be able to bring back extinct animals, and perhaps early humans, raising questions of ethics and environmental disruption.

(PhysOrg.com) -- A new study of thousands of species of plants and animals suggests new species may arise from rare events instead of through an accumulation of small changes made in response to changes in the environment.
(Physorg.com) -- Humans have actively changed the coats of domestic animals by cherry-picking rare genetic mutations, causing variations such as different colours, bands and spots, according to a new study.
