The ancient human fellowship tree diagram is complicated . An evolutionary flight that was once presented as a straight line has been abandoned , and our history is image as a " muddy delta " or " braided stream " representing the interplay between forcible and ethnic adaptations across species . The story of theHomogenus is a saga that cross more than 2 million year and at least three continents , demonstrating our ancestors ' ability to adapt to well-nigh any surround .

Africa
Homo habilis
key " jack of all trades " in 1964 because of stone creature found with its clay , Homo habilisflourished in Eastern and Southern Africa from 2.4 million to 1.4 million years ago . With a slightly larger brain than sometime human relatives ' and an copycat - similar face , H. habilisstood about 4 feet ( 1.2 meter ) tall , on average , and ate a fairly omnivorous dieting . H. habiliswas long assumed to be the earliest transmissible member of our genus , but this word picture is being questioned as new dating techniques have shown thatH. erectusis evenolder than previously thoughtand perhaps unrelated toH. habilis .
Homo erectus
Homo habilis
This wildly successful coinage , known both asHomo erectusandHomo ergaster , originated at least 2 million age ago and survived until110,000 year ago . As the early species to have human - like body proportions — the marvellous of them reaching 6 feet ( 1.8 m ) and 150 Sudanese pound ( 68 kilograms ) — H. erectusneeded a lot of get-up-and-go to power both its consistency and its large brain . H. erectusdeveloped specialized shaft , figure out how to make attack to fix meat , and began exploring the world , leaving Africa and reaching as far as East Asia before either disappearing or evolve into other coinage .
human being naledi
Discovered in a South African cave system in 2013,Homo nalediis one of the more mysterious members of our genus . Dating back to around 335,000 to 236,000 year ago , H. nalediwalked on two feet but was also well adjust for mounting trees . At about 4 foot , 9 inches ( 1.4 thou ) and 88 pound ( 40 kg),H. nalediwas a petite , small - brain hominin . Without grounds of Lucy Stone tools or other culture , piffling is known aboutH. naledi ’s lifestyle , although researchers have controversiallysuggestedthat theyburied their deadand made cave art . It is unclear where , exactly , H. naledifits in theHomofamily Sir Herbert Beerbohm Tree .
Homo erectus
Europe and Asia
Homo heidelbergensis
Likely germinate fromH. erectusin Africa , Homo heidelbergensiswas the first hominin to settle in colder climates , including in Europe . live around 700,000 to 200,000 class ago , these hominins probably looked similar to their ascendant and used their big brains tocreate early shelters , hunting turgid animalsand perhaps evenritually bury their dead . DNA evidence suggests that Neanderthals and modern humansdiverged from a common ancestorand points toH. heidelbergensisas thespecies that led to our own .
Homo neanderthalensis
Homo naledi
Neanderthalsevolved fromH. heidelbergensisaround 400,000 years ago , accord to the most late enquiry . Closely related to us , Neanderthals had an even more sophisticated finish , which included stone tool andperhaps spelunk prowess , than their ancestors . They looked like a slightly short , slimly thick version of human , with a larger midface neighborhood , all of which made them well adapt for natural selection in the cold climates of Europe and Western Asia . The cause of Neanderthals ' extinction has been debated for decades , but DNA research has revealed that they definitelyinterbred with advanced humansand that many of us gestate loutish gene . For this ground , some research worker think Neanderthals should be in the category ofHomo sapienswith us .

Denisovans
Homo neanderthalensis
When a little handful of fossil were discovered in a Siberian cave in 2010 , identification of the accurate species was indecipherable . Dating from 194,000 to 51,000 age ago , the Denisova hominins are oracular , and the only genuine information about them has come throughDNA analysis . Scientists bed thatDenisovanswere intimately related to both Neanderthals and modern humans , as there is grounds of interbreeding , specially with former humans inSoutheast Asia . Currently , there is not enough fogy stuff for the Denisovans to justify their own metal money name . But since some of their genes have been found in mod world , they — like Homo sapiens neanderthalensis — could even be considered part of our own species . Regardless of what we call them , it is clean they are part of theHomogenus .
Pacific Islands
Homo floresiensis
As inquiry procession on Denisovans and hominin fossil in Southeast Asia , the position of other species in theHomofamily tree may become decipherable . In 2003 , specimens of a very low hominin were get word in a cave on the island of Flores in Indonesia . find with stone dick , H. floresiensislived between 100,000 and 50,000 age ago . Even though they stood only around 3 feet , 6 inch ( 1 m ) tall , the member of this species otherwise attend a stack likeH. erectus . The current hypothesis is that they descended fromH. erectusand evolved to have small bodiesdue to parochial nanism , an evolutionary adaptation to the deficiency of resource on the island . Because of their size of it , H. floresiensismembers are often referred to as " hobbits . "

With longer finger and toe than innovative humans ' and distinct tooth , it is unreadable where , exactly , H. luzonensissits in theHomogenus . The fogy bones date stamp to 67,000 years ago , which evince that early hominins sleep together how to make open - sea crossings , but Luzon has also produceddozens of endocarp tools and butcher rhinoceros bonesthat leave circumstantial grounds that a hominin antecedent was be there as far back as 709,000 years ago .

Homo sapiens
Skulls ofHomo floresiensisvs.Homo sapiens
Modern humans , Homo sapiens , seem to haveappeared in Africa at least 300,000 years ago , likely due to the ability to accommodate to an unstable and promptly changing environment . Our species has a slimmer build than our ascendent did , as well as a very large brain contain in a round skull with a eminent , two-dimensional forehead . H. sapienshas survived by spreading throughout the earth , accommodate to environments place from spicy , humid jungles to cold , desiccate tundra , chiefly through ethnic , rather than physical , version . But our story is n’t over yet , as we have n’t stop acquire — we ’ve gotten better atfighting off sealed pathogens , for example — and manyresearchers have shownthat , in fact , the recent genetic evolution of our metal money has been inordinately rapid .
