How many species of hominids were there? What did early Homo sapiens look like? What does the word 'Homo sapiens' mean? How did Homo erectus differ from modern Homo sapiens? Did Homo erectus evolve into Homo sapiens? How many species of hominin coexisted 100,000 years ago? How old is H...
Prior to Lucy, the oldest known human fossil—a 2.5-million-year-old skull recovered from a cave in South Africa—was from an ape-like hominin species called Australopithecus africanus. But Johanson’s hominins dated nearly a million years earlier and came from East Africa, a completely differen...
Below is a hypothetical phylogenetic tree. Use this tree to answer the following questions based on these provided data. A. How many years ago did species M and N diverge from their most recent common ancestor? B. How much nucleotide divergence is there b ...
The next hominin to appear wasHomo heidelbergensis. It evolved from aHomo erectuspopulation in Africa about 600,000 years ago. This species’ hyoid – a small bone with an important role in our vocal apparatus – is virtually indistinguishable from ours, and its ear anatomy suggests it would h...
In the late 2000s, Russian archeologists made a surprising discovery: They found a new species of archaic human. They named it “The Denisovan”, after the Denisova cave where it was found. The cave’s location is in the Altai mountains in Siberia. ...
This month saw half of the world’s population enter some form of confinement, and many people are facing the biggest threat to their health and livelihood in recent history. “We are seeing the spread of a virus, but we have also, from the very beginning, been seeing the s...
In reality, the fact that there are no other species alive today that look like modern humans is a good indication that the reason we look the way we do is "just a fluke of evolution," he added. "While there are many, many cases of convergent evolution of other adaptations, for some...
In drawing such inferences, researchers implicitly assume that either there is little variation across human populations, or that WEIRD populations are generally representative of the species. Yet neither of these assumptions is justified. In many psychological and behavioural domains, cultural variation ...
6 and 8 million years ago. for the next few million years, the brains of early hominins did not grow much larger than those of our ape ancestors and cousins. starting around 3 million years ago, however, the hominin brain began a massive expansion. by the time our species, homo sapiens...
We do not know which species of predator caused the bite, but the wound from the failed attack is a smoking gun. It is possible thatSinosaurus, a well-known predator found in Jurassic Yunnan, would have been able to attackLufengosaurus. ...
