One of the most startling discoveries in the study of human origins -- the uncovering of a vanished species of dwarf proto-humans who inhabited a Pacific island just 18,000 years ago -- is being reported in today&#39;s issue of the journal Nature.

By Eric Sharp, Detroit Free Press  Sep. 23--The other day, a fisheries scientist was marveling at how pink salmon, after being landlocked in the Great Lakes for only 50 years, have evolved to a three-year life cycle, while pinks in their original Pacific Ocean homeland live only two years.

Parents have been doting over their offspring for a very, very long time, it seems. A South African fossil suggests pelycosaurs -- intermediates between reptiles and mammals that lived in the Permian Period before the rise of dinosaurs -- may have been caring parents 260 million years ago, scientists said on Wednesday.
