Museums house thousands of animal specimens that are ancient, extinct, newly discovered and have yet to be studied. New York's American Museum of Natural History has 33 million specimens inside, while the Smithsonian's National Museum of Natural History in Washington D.C. has a whopping 145 million holdings.While most animals collected by these institutions have been obtained legally, euthanized painlessly and researched with respect, some researchers often wonder whether there could be a better ...read more
We like to think of ourselves as special. We’re Homo sapiens, after all. But a new study of Ice Age Europe has found that our supposedly unique bone tools, a sign of higher intelligence, weren’t so unique after all. Neanderthals fashioned and used hundreds of the same tools while butchering animals and preparing hides, according to a new paper.Evidence for this has arisen, in recent years, from two Neanderthal sites of some note – starting with the Chagyrskaya Cave in the Altai Mountains i ...read more
Although dirt doesn’t seem to be particularly interesting on the surface — we often picture a lifeless, unremarkable substance beneath our feet — it’s actually a dynamic ecosystem teeming with organisms. And these organisms hold the power to make or break all of life on Earth.One such unsung hero is the humble earthworm and, most importantly, its toilet habits. If you plop your spade into a patch of healthy soil, chances are that most of this is stuff that's come out the back end of an e ...read more
Humans lived in South America many thousands of years earlier than previously believed, during the height of the Last Ice Age. A new archaeological study discovered this by analyzing a trio of necklaces made from ground sloth bones. The project wades into an ongoing debate over when and how Homo sapiens, who evolved in Africa and first spread to Europe and Asia, made it to the relatively remote Americas.How Did Humans Settle the Americas?In the conventional view of American settlement, human bei ...read more
A female American crocodile has spent her entire life in captivity in a reptile park in Costa Rica and just laid several fertile eggs — without mating first.This recent event means that researchers are now adding crocodilians to a growing list of birds, reptiles, amphibians and fish that can generate offspring without the help of a male mate.“It’s likely that this has happened for thousands and thousands of years and [has] just been missed,” says Warren Booth, an evolutionary biologist a ...read more
