Oct 21, 2024 · Human evolution, the process by which human beings developed on Earth from now-extinct primates. The only extant members of the human tribe, Hominini, belong to the species Homo sapiens. The exact nature of the evolutionary relationships between modern humans and their ancestors remains the subject of debate.

Oct 11, 2023 · Since then, multiple branches in the tree of human evolution have come and gone, while some had descendants who evolved into species that eventually became modern humans. What Is Human Evolution? Human evolution refers to the long and complex process by which modern humans, Homo sapiens , have developed from earlier, more primitive species of hominins (the group that includes modern humans and ...

First things first: A “human” is anyone who belongs to the genus Homo(Latin for “man”). Scientists still don’t know exactly when or how the first humans evolved, but they’ve identified a few of the oldest ones. One of the earliest known humans is Homo habilis, or “handy man,” who lived about 2.4 million to 1.4 million years ago in Eastern and South...
After the superarchaic humans came the archaic ones: Neanderthals, Denisovans and other human groups that no longer exist. Archaeologists have known about Neanderthals, or Homo neanderthalensis, since the 19th century, but only discovered Denisovans in 2008 (the group is so new it doesn’t have a scientific name yet). Since then, researchers have di...
Scientists are still figuring out when all this inter-group mating took place. Modern humans may have mated with Neanderthals after migrating out of Africa and into Europe and Asia around 70,000 years ago. Apparently, this was no one-night stand—research suggeststhere were multiple encounters between Neanderthals and modern humans. Less is known ab...
Human groups that encountered each other probably swapped more than just genes, too. Neanderthals living in modern-day France roughly 50,000 years ago knew how to start a fire, according to a 2018 Nature paperon which Sorensen was the lead author. Fire-starting is a key skill that different human groups could have passed along to each other—possibl...

- 300,000 Years Ago: Artifacts Show a Revolution in Tools. Our ancestors used stone tools as long as 3.3 million years ago and by 1.75 million years ago they’d adopted the Acheulean culture, a suite of chunky handaxes and other cutting implements that remained in vogue for nearly 1.5 million years.
- 100,000 to 210,000 Years Ago: Fossils Show Homo sapiens Lived Outside of Africa. Many genetic analyses tracing our roots back to Africa make it clear that Homo sapiens originated on that continent.
Genetic data can provide important insight into human evolution. In May 2023, scientists reported a more complicated pathway of human evolution than previously understood. According to the studies, humans evolved from different places and times in Africa, instead of from a single location and period of time. [274] [275]
Oct 21, 2024 · Human evolution - Emergence, Homo Sapiens, Bipedalism: The relationships among Australopithecus, K. platyops, Paranthropus, and the direct ancestors of Homo are unknown. Because of its early date and geographic location, A. anamensis may be the common ancestor of A. afarensis, A. garhi, K. platyops, and perhaps the Laetoli Pliocene hominins of eastern Africa, A. bahrelghazali of central Africa ...

Many evolutionary changes occurred at this stage: eyelids and tear glands evolved to keep the eyes wet out of water and the eyes became connected to the pharynx for draining the liquid; the hyomandibula (now called columella) shrank into the spiracle, which now also connected to the inner ear at one side and the pharynx at another, becoming the Eustachian tube (columella assisted in hearing ...
