Feathers, fur, and scales: Do they share a common ancestry?
A bird's feathers, a reptile's scales, and a mammal's hairs may seem like very distinct features, but these skin appendages may come from common origins, say scientists.The mechanism behind the embryonic development of feathers, reptilian scales, and hair is remarkably similar, according to a paper published Friday in the journal Science Advances. This finding suggests that these distinct appendages have their roots in a common ancestor of these three diverse lineages."This doesn't imply at all..>> view originalOld Monkeys are like Elderly Humans; Both Get More Selective as They Get Old
Old monkeys have a similarity with old humans: both have fewer friends. A new study has suggested that during old age, monkeys isolate themselves, like older humans do. At that time, they become more selective when it comes to choose friends. For the study published in Current Biology, a team of researchers from the German Primate Center analyzed social behavior in over 100 monkeys. These were Barbary macaque monkeys, ranged in age from 4 to 29, from a southern French park. The researche..>> view originalAppearance Of 'Watermelon Snow' Important In Studying Melting Glaciers
