Nice try, but not quite. We are learning Neanderthals were just as innovative and sophisticated as we fancy ourselves to be — raising questions about what it means to be human.
A tiny, engraved bone is changing how we think about Neanderthals, the heavily built Stone Age hominins who disappeared about 40,000 years ago.
It’s a phenomenon shared by other planets in our solar system, including the largest, Jupiter, which is bathed in spectacular color at its poles.
Characterized by massive pulsating X-ray flares, Jupiter’s northern lights were first discovered 40 years ago. Astronomers have long sought to explain the mechanism behind these auroras.
Plastic waste is a visible way humans contaminate rivers and oceans, but less noticeable forms of pollution can be just as perilous for aquatic life.
In the study, the scientists found brown trout living in a tank of water containing methamphetamine for a period of eight weeks sought out water containing the drug — when given a choice — for four days after being transferred to meth-free water.
This behavior suggested the fish were experiencing withdrawal because they sought out the drug when it became available, according to researchers.
Scientists have pored over more than 300 fossils belonging to different members of the Homo genus, or the human family tree — including us, Homo sapiens — and reconstructed the Earth’s climate to see what conditions were like when these different species of human lived.
Colder, harsher climates were linked to larger bodies, such as those of well-built Homo neanderthalensis, while warmer climates were linked to smaller bodies, the scientists found.
For now, the team said, it’s unlikely that the current, human-induced climate crisis will dramatically impact our body sizes.
Here are some more mind-blowing reads.
