Human evolution
Human evolution is the evolutionary process within the history of primates that led to the emergence of Homo sapiens as a distinct species of the hominid family, which includes all the great apes. This process involved the gradual development of traits such as human bipedalism, dexterity and complex language, as well as interbreeding with other hominins (a tribe of the African hominid subfamily), indicating that human evolution was not linear but weblike. The study of human evolution involves several scientific disciplines, including physical and evolutionary anthropology, paleontology, and genetics.Primates diverged from other mammals about (mya), in the Late Cretaceous period, with their earliest fossils appearing over 55 mya, during the Paleocene. Primates produced successive clades leading to the ape superfamily, which gave rise to the hominid and the gibbon families; these diverged some 15–20 mya. African and Asian hominids (including orangutans) diverged about 14 mya. Hominins (including the Australopithecine and Panina subtribes) parted from the Gorillini tribe (gorillas) between 8–9 mya; Australopithecine (including the extinct biped ancestors of humans) separated from the Pan genus (containing chimpanzees and bonobos) 4–7 mya. The Homo genus is evidenced by the appearance of H. habilis over 2 mya, while anatomically modern humans emerged in Africa approximately 300,000 years ago.

Big freeze drove early humans out of Europe
Science correspondentA big freeze previously unknown to science drove early humans from Europe for 200,000 years, but they adapted and returned, new research shows.Ocean sediments from 1.1 million years ago show temperatures suddenly dropped more than 5C, scientists say.

Why don't humans have fur?
If an alien race came to Earth and lined up humans in a row alongside all the other primates, one of the first differences they might observe – together with our upright position and unique form of communication – is our apparently furless bodies.
Ancient stone tools found in Kenya made by early humans
Archaeologists in Kenya have dug up some of the oldest stone tools ever used by ancient humans, dating back around 2.9 million years. It is evidence that the tools were used by other branches of early humans, not just the ancestors of Homo Sapiens.
Nobel Prize goes to Svante Paabo for Neanderthal work
The Nobel Prize in Physiology or Medicine has gone to Sweden's Svante Paabo for his work on human evolution. The Prize committee said he achieved the seemingly impossible task of cracking the genetic code of one of our extinct relatives - Neanderthals.
Here's what we know sex with Neanderthals was like
As we end another extraordinary year and start a new one, BBC Future is taking a look back at some of our favourite stories for our "Best of 2021" collection. Discover more of our picks here. Their eyes met across the rugged mountain landscape of prehistoric Romania.
Denisovans: Face of long-lost human relative unveiled
Researchers have provided the first glimpse of what an ancient group of humans looked like. Denisovan remains were discovered in 2008 and human evolution experts have become fascinated with the group that went extinct around 50,000 years ago.
The man who can remember every day of his life
Bob Petrella can recall any moment from his past. Called highly superior autobiographical memory, there are around 60 known cases around the world. “It’s almost like having a time machine, where I can go back to a certain day or a certain period in my life and almost feel like I’m back there.
From The Conversation
Reader Question: We now know from evolutionary science that humanity has existed in some form or another for around two million years or more. Homo sapiens are comparatively new on the block. There were also many other human species, some which we interbred with.
Scientists hail stunning 'Dragon Man' discovery
Chinese researchers have unveiled an ancient skull that could belong to a completely new species of human. The team has claimed it is our closest evolutionary relative among known species of ancient human, such as Neanderthals and Homo erectus.
Israel cave bones: Early humans 'conserved food to eat later'
Scientists in Israel say they have found evidence that early humans deliberately stored bones from animals to eat the fatty marrow later. It is the earliest evidence that humans living between 200,000 and 420,000 years ago had the foresight to anticipate future needs, they say.
New type of ancient human discovered in Israel
Researchers working in Israel have identified a previously unknown type of ancient human that lived alongside our species more than 100,000 years ago. They believe the remains uncovered near the city of Ramla represent one of the "last survivors" of a very ancient human group.
Ancient Jersey teeth find hints at Neanderthal mixing
Prehistoric teeth unearthed at a site in Jersey reveal signs of interbreeding between Neanderthals and our own species, scientists say. UK experts re-studied 13 teeth found between 1910 and 1911 at La Cotte de St Brelade in the island's south-west.
Why humans have evolved to drink milk
Dairy milk has competition. Alternative “milks” made from plants like soya or almonds are increasingly popular. These alternatives are often vegan-friendly and can be suitable for people who are allergic to milk, or intolerant of it.
Anatomical clues to human evolution from fish
It may seem strange that humans have evolved from fish, but the evidence can be found not just in fossils but also within our own bodies. Your face is your most expressive feature; it tells the world what you are feeling, who you are and where you come from.
Teeth and jaw are from 'earliest Europeans'
Two baby teeth and a jaw fragment unearthed in Italy and the UK have something revealing to say about how modern humans conquered the globe. The finds in the Grotta del Cavallo, Apulia, and Kents Cavern, Devon, have been confirmed as the earliest known remains of Homo sapiens in Europe.
Why is there only one human species?
Not so very long ago, we shared this planet with several other species of human, all of them clever, resourceful and excellent hunters, so why did only Homo sapiens survive?
'Astonishing' skull unearthed in Africa
This is a picture of the recently unearthed human-like skull which is being described as the most important find of its type in living memory. It was found in the desert in Chad by an international team and is thought to be approximately seven million years old. "I knew I would one day find it...
'Hobbit' human 'is a new species'
The tiny skeletal remains of human "Hobbits" found on an Indonesian island belong to a completely new branch of our family tree, a study has found. The finds caused a sensation when they were announced to the world in 2004.
'Hobbit' island's deeper history
Long before a 'hobbit' species of human lived on Indonesia's Flores island, other human-like creatures colonised the area. That much was clear. The group says the finds bring a new dimension to our understanding of the history of Flores.
'Lucy's baby' found in Ethiopia
The 3.3-million-year-old fossilised remains of a human-like child have been unearthed in Ethiopia's Dikika region. The female Australopithecus afarensis bones are from the same species as an adult skeleton found in 1974 which was nicknamed "Lucy".
Age of ancient humans reassessed
Two skulls originally found in 1967 have been shown to be about 195,000 years old, making them the oldest modern human remains known to science. The age estimate comes from a re-dating of Ethiopian rock layers close to those that yielded the remarkable fossils.
African fossils put new spin on human origins story
The ancient remains of two human-like creatures found in South Africa could change the way we view our origins. The 1.9-million-year-old fossils were first described in 2010, and given the species name Australopithecus sediba.
