Apart from our species, the gallery features eight other kinds of human: Homo habilis, Homo rudolfensis, Homo erectus, Homo antecessor, Homo heidelbergensis, Homo floresiensis (nicknamed 'the hobbit'), Homo neanderthalensis (the Neanderthals) and the recently discovered Homo naledi.
By the time Homo sapiens arrived on the scene some 300,000 years ago, we were the ninth Homo species, joining habilis, erectus, rudolfensis, heidelbergensis, floresiensis, neanderthalensis, naledi, and luzonensis.
Nine human species walked the Earth 300,000 years ago. Now there is just one. The Neanderthals, Homo neanderthalensis, were stocky hunters adapted to Europe's cold steppes. The related Denisovans inhabited Asia, while the more primitive Homo erectus lived in Indonesia, and Homo rhodesiensis in central Africa.
The extinct ancient human Homo erectus is a species of firsts. It was the first of our relatives to have human-like body proportions, with shorter arms and longer legs relative to its torso.
When did Neanderthals live? The Neanderthals have a long evolutionary history. The earliest known examples of Neanderthal-like fossils are around 430,000 years old. The best-known Neanderthals lived between about 130,000 and 40,000 years ago, after which all physical evidence of them vanishes.
Homo sapiens is currently the only member of the genus Homo alive. There's only one species of human—but it wasn't always so.
New research suggests some of our species' closest relatives died out because of significant changes in climate, findings that may offer a warning for humanity today. Several close relatives of our species, Homo sapiens, have walked this Earth since the genus Homo evolved more than 2 million years ago.

Homo sapiens, the first modern humans, evolved from their early hominid predecessors between 200,000 and 300,000 years ago. They developed a capacity for language about 50,000 years ago. The first modern humans began moving outside of Africa starting about 70,000-100,000 years ago.
Abstract. Using gene frequency data for 62 protein loci and 23 blood group loci, we studied the genetic relationship of the three major races of man, Caucasoid, Negroid, and Mongoloid. Genetic distance data indicate that Caucasoid and Mongoloid are somewhat closer to each other than to Negroid.
Changing Human DNA to Neanderthal DNA
The most likely way to bring back a Neanderthal with today's technology is to start out with a human cell and slowly, bit by bit, change it into a Neanderthal one. Most likely we would do this with something called CRISPR/Cas9.
The Neanderthal hyoid bone
Its similarity to those of modern humans was seen as evidence by some scientists that Neanderthals possessed a modern vocal tract and were therefore capable of fully modern speech.
One model postulates that habitat degradation and fragmentation occurred in the Neanderthal territory long before the arrival of modern humans, and that it led to the decimation and eventual disappearance of Neanderthal populations.
The physical traits of Homo sapiens include a high and rounded ('globular') braincase, and a relatively narrow pelvis. Measurement of our braincase and pelvic shape can reliably separate a modern human from a Neanderthal - their fossils exhibit a longer, lower skull and a wider pelvis.
Genetic studies have demonstrated that humans are still evolving. To investigate which genes are undergoing natural selection, researchers looked into the data produced by the International HapMap Project and the 1000 Genomes Project.
There is nothing new about humans and all other vertebrates having evolved from fish. The conventional understanding has been that certain fish shimmied landwards roughly 370 million years ago as primitive, lizard-like animals known as tetrapods.
A new genetic study suggests all modern humans trace our ancestry to a single spot in southern Africa 200,000 years ago.
Endangered Species: Humans Might Have Faced Extinction 1 Million Years Ago. New genetic findings suggest that early humans living about one million years ago were extremely close to extinction.
The last “sympatric” humans we know of were Neanderthals, who became extinct only about 30,000 years ago. Since stable separation of parts of the species is the key factor for the formation of new species, we can say that a new split of our species is impossible under current circumstances.
Around 70,000 years ago, humanity's global population dropped down to only a few thousand individuals, and it had major effects on our species. One theory claims that a massive supervolcano in Indonesia erupted, blackening the sky with ash, plunging earth into an ice age, and killing off all but the hardiest humans.
Basic math tells us that all humans share ancestors, but it's amazing how recently those shared ancestors lived. Thanks to genetic data in the 21st century, scientists are discovering that we really are all descended from one mother.
Humans and monkeys are both primates. But humans are not descended from monkeys or any other primate living today. We do share a common ape ancestor with chimpanzees. It lived between 8 and 6 million years ago.
Today, all humans are classified as belonging to the species Homo sapiens.
