When did Homo heidelbergensis emerge?
Around 700,000 years ago (and perhaps as early as 780,000 years ago), Homo heidelbergensis had developed from Homo erectus. In Africa, they were part of a gradual, mosaic -like transition into the earliest Homo sapiens around roughly 200,000 years ago.
What is the difference between Homo heidelbergensis and Neanderthal?
European populations of Homo heidelbergensis evolved into Homo neanderthalensis (the Neanderthals) while a separate population of Homo heidelbergensis in Africa evolved into our own species, Homo sapiens. Some European fossils have features that indicate they were intermediate between earlier Homo heidelbergensis and the later Neanderthal people.
Where did the Heidelberg Man come from?
Named for a piece of jawbone found near Heidelberg, Germany, these hominins occupy an intriguing and much-discussed spot in the jumble of human evolution; they are most commonly seen to have developed from Homo erectus and to have given rise to Homo sapiens in Africa and to the Neanderthals in Europe.
What are the characteristics of Homo heidelbergensis fossils?
Homo heidelbergensis fossils tend to have features that are intermediate between those of Homo ergaster and either Homo neanderthalensis or Homo sapiens.
What did Homo heidelbergensis evolve into?
Homo heidelbergensis began to develop regional differences that eventually gave rise to two species of humans. European populations of Homo heidelbergensis evolved into Homo neanderthalensis (the Neanderthals) while a separate population of Homo heidelbergensis in Africa evolved into our own species, Homo sapiens.
Where did Homo heidelbergensis come from?
Homo heidelbergensis, extinct species of archaic human (genus Homo) known from fossils dating from 600,000 to 200,000 years ago in Africa, Europe, and possibly Asia.
When did Homo heidelbergensis evolve?
between 350,000 and 400,000 years agoEvolutionary Tree Information: Comparison of Neanderthal and modern human DNA suggests that the two lineages diverged from a common ancestor, most likely Homo heidelbergensis, sometime between 350,000 and 400,000 years ago – with the European branch leading to H.
When did Homo heidelbergensis first appear?
The earliest discoveries of H. heidelbergensis are from Germany. The type specimen was discovered in 1907 in Mauer, Germany. The oldest site is Bodo, Ethiopia (600 kya).
What did African H. erectus evolve from?
H. habilisIt has been proposed that H. erectus evolved from H. habilis about 2 Mya, though this has been called into question because they coexisted for at least a half a million years. Alternatively, a group of H. habilis may have been reproductively isolated, and only this group developed into H. erectus (cladogenesis).
When did the first human species evolve?
Viewed zoologically, we humans are Homo sapiens, a culture-bearing upright-walking species that lives on the ground and very likely first evolved in Africa about 315,000 years ago.
Who is the oldest ancestor and when were they around?
Ardipithicines. Ardipithecus is the earliest known genus of the human lineage and the likely ancestor of Australopithecus, a group closely related to and often considered ancestral to modern human beings. Ardipithecus lived between 5.8 million and 4.4 million years ago.

Where did H. heidelbergensis originate?
As for its evolution, H. heidelbergensis is thought to have descended from African H. erectus —sometimes classified as Homo ergaster —during the first early expansions of hominins out of Africa beginning roughly 2 million years ago. Those that dispersed across Europe and stayed in Africa evolved into H. heidelbergensis or speciated into H. heidelbergensis in Europe and " H. rhodesiensis " in Africa, and those that dispersed across East Asia evolved into H. erectus s. s. The exact derivation from an ancestor species is obfuscated by a long gap in the human fossil record near the end of the Early Pleistocene. In 2016, Antonio Profico and colleagues suggested that 875,000 year old skull materials from the Gombore II site of the Melka Kunture Formation, Ethiopia, represent a transitional morph between H. ergaster and H. heidelbergensis, and thus postulated that H. heidelbergensis originated in Africa instead of Europe.
What are the characteristics of H. heidelbergensis?
They listed the diagnostic traits as: a reduced chin, a notch in the submental space (near the throat), parallel upper and lower boundaries of the mandible in side-view, several mental foramina (small holes for blood vessels) near the cheek teeth, a horizontal retromolar space (a gap behind the molars), a gutter between the molars and the ramus (which juts up to connect with the skull), an overall long jaw, a deep fossa (a depression) for the masseter muscle (which closes the jaw), a small gonial angle (the angle between the body of the mandible and the ramus), an extensive planum alveolare (the distance from the frontmost tooth socket to the back of the jaw), a developed planum triangulare (near the jaw hinge), and a mylohyoid line originating at the level of the 3rd molar.
What technology did the Middle Pleistocene use?
The Middle Pleistocene of Africa and Europe features the advent of Late Acheulian technology, diverging from earlier and contemporary H. erectus, and probably related to increasing intelligence. Fire likely became an integral part of daily life after 400,000 years ago, and this roughly coincides with more permanent and widespread occupation of Europe (above 45°N ), and the appearance of hafting technology to create spears. H. heidelbergensis may have been able to carry out coordinated hunting strategies, and similarly they seem to have had a higher dependence on meat.
Where is the Mauer mandible?
The palaeontology institute at Heidelberg University, where the Mauer mandible has been kept since 1908, changed the label from H. e. heidelbergensis to H. heidelbergensis in 2015. Cast of Sima de los Huesos Skull 5 (" Miguelón ") at the Natural History Museum, London.
Where did the H. antecessor originate?
antecessor from Gran Dolina, Sierra de Atapuerca, and suggested supplanting this species in the place of H. heidelbergensis for the LCA between modern humans and Neanderthals, with H. heidelbergensis descending from it and being a strictly European species ancestral to only Neanderthals. They later recanted. In 2020, Danish geneticist Frido Welker and colleagues analysed ancient proteins collected from an H. antecessor tooth found that it was a member of a sister lineage to the LCA rather than being the LCA itself (that is, H. heidelbergensis did not derive from H. antecessor ).
Why did Neanderthals have higher rates of hypoplasia?
Nonetheless, Neanderthals suffered even higher rates and more intense bouts of hypoplasia, but it is unclear if this is because Neanderthals were less capable of exploiting natural resources, or because they lived in harsher environments. A peak at 3.5 years of age may be correlated with weaning age.
When did humans disperse?
Human dispersal beyond 45°N seems to have been quite limited during the Lower Palaeolithic, with evidence of short-lived dispersals northward beginning after a million years ago. Beginning 700,000 years ago, more permanent populations seem to have persisted across the line coinciding with the spread of hand axe technology across Europe, possibly associated with the dispersal of H. heidelbergensis and behavioural shifts to cope with the cold climate. Such occupation becomes much more frequent after 500,000 years ago.
When did Homo Heidelbergensis go extinct?
Full Article. Homo heidelbergensis, extinct species of archaic human (genus Homo) known from fossils dating from 600,000 to 200,000 years ago in Africa, Europe, and possibly Asia.
Where did H. heidelbergensis occur?
heidelbergensis is the common ancestor of both Neanderthals and modern humans and that the transition from H. heidelbergensis to H. sapiens occurred in Africa prior to 300,000 years ago. Henry McHenry.
How long ago was the pelvis of H. heidelbergensis?
human evolution: The fossil evidence. The pelvis of H. heidelbergensis (600,000–200,000 years ago, or 600–200 kya) and that of Neanderthals (200–30 kya) are distinct from the pelvis of H. sapiens in some features that recall those of Australopithecus. The pelvis is broad, with ilia flaring out to the side. The femoral necks are….
What is the Heidelberg jaw?
The Heidelberg jaw, also called the Mauer jaw, lacks a chin and is exceptionally thick and broad. The teeth are surprisingly small for such a massive mandible. The jaw is also long, and this feature may imply that the individual had a projecting lower face.
Where are Homo sapiens found?
Sites of Homo heidelbergensis and Homo sapiens remains in Africa, Europe, and Asia. Encyclopædia Britannica, Inc. Until the 1990s it was common to place these specimens either in H. erectus or into a broad category along with Neanderthals that was often called archaic H. sapiens.
Where was the Heidelberg jaw found?
Among the fossils found with the Heidelberg jaw were those of several extinct mammals that lived about 500,000 years ago. The Kabwe cranium, found in 1921 at Broken Hill, Northern Rhodesia (now Kabwe, Zambia), and originally called Rhodesian man. The skull is now considered to be representative of Homo heidelbergensis.
Where did modern anatomy come from?
sapiens lineage. Indeed, the first intimations of our distinctively modern anatomy come from southern and eastern Africa only in the period between about 160 and….
What were Homo Heidelbergensis tools used for?
The tools made by Homo heidelbergensis were mostly used for hunting and butchery. Most of their tools were of the type previously used by Homo ergaster. These were large stone tools with flakes removed from two sides to produce the bifacial stone hand axes, cleavers and carvers classified as Mode 2 technology.
How long ago did the hominin live?
The only species in this genus, this hominin lived about 3 million years ago. However, the species name is based on a distorted and fragmented skull and many debate its validity.
How old are African fossils?
The African fossils tend to be older than those from Europe. Fossils from Gran Dolina in Spain date to 800,000 years old, and may be Homo heidelbergensis or a different species, Homo antecessor. In 1907, an ancient human jaw was discovered in a quarry at Mauer, a village near Heidelberg, Germany.
Why was the ape first rejected from the family tree?
This species was the first of our pre-human ancestors to be discovered, but was initially rejected from our family tree because of its small brain. This opinion changed when new evidence showed this species had many features intermediate between apes and humans.
Which bone tended to be thick and strongly built?
leg bones tended to be thick and strongly built.
Where are the remains of the oldest human remains?
The remains of at least 6 individuals found at the site of Gran Dolina, Atapuerca, in Spain. They lived about 800,000 to 1 million years ago in Europe and are the oldest human remains found in that continent.
Where was the skull found?
Cast of a skull discovered in 1933 in Steinheim, Germany. It dates to about 250,000 years old. The face of the Steinheim skull is shaped like those of other Homo heidelbergensis individuals although it is less robust and may belong to an adult female. The cranium, however, is Neanderthal-like as it is very rounded at the rear ...
Where did H. heidelbergensis evolve?
The other more popular scenario has H. heidelbergensis evolving in Africa from some descendant form of Homo ergaster. A portion of the population then emigrated to Europe and evolved into neandertals while a portion of the remaining African stock evolved toward AMH.
What is the phylogeny of H. heidelbergensis?
PHYLOGENY. H. heidelbergensis is thought to have evolved from a more derived form of H. ergaster. Some researchers believe that the material from Tighenif (formerly Ternifine), Algeria, known by some as Homo mauritanicus, is a possible transitional form between the two species.
What are the characteristics of Neandertals?
Review of Characteristics Inherited by Neandertals 1 Midfacial prognathism and large nose. 2 Puffy appearance to face due to large frontal and maxillary sinuses. 3 “Swept back” zygomatics. 4 Occipital bun. 5 Thick cortical bone and narrow medullary cavity.
How is H. heidelbergensis distinguished from erectus?
H. heidelbergensis is primarily distinguished from erectus -like forms by its increased cranial capacity (1100–1400 cc—93% that of AMH) and more modern skull vault.
Where did the Denisovans come from?
heidelbergensis. The Denisovans (see this chapter), as they have come to be known due to their discovery in the Denisova Cave in the Altai Mountains of Russia, are thought to have branched off from the H. heidelbergensis lineage that led to neandertals. DNA analyses show that Denisovans interbred with neandertals, as well as the first wave of AMH that left Africa, possibly around 125 kya and subsequently settled Melanesia and Australia.
Is H. heidelbergensis a common ancestor?
Contrary new DNA evidence suggests that H. heidelbergensis branched off from some common ancestors prior to 800 kya and is thus not part of our recent lineage. H. heidelbergensis then divided into the neandertals and the Denisovan lineages, but interbreeding continued between them in areas of geographic overlap.
Is H. heidelbergensis ancestral to humans?
It is now well accepted that H. heidelbergensis was ancestral to both humans and neandertals (see Figure 33.2—note that in this scenario, H. antecessor is not considered to be ancestral to H. heidelbergensis ). Human phylogeny. “ Homo-Stammbaum, Version Stringer ” by Chris Stringer is licensed under CC BY-SA 3.0 DE.
Where was the first evidence of Homo heidelbergensis found?
A mandible found in Germany, the first evidence of Homo heidelbergensis. (Credit: Gerbil/Wikimedia Commons) Between H. erectus and H. sapiens, intermediate species existed, variably named Homo heidelbergensis, Homo rhodesiensis or Homo antecessor, depending on a researcher’s views. Many anthropologists just call the whole bunch Middle Pleistocene ...
How long ago did Homo erectus live?
Most anthropologists agree that if you traced your ancestry back about 1 million years, you’d find a population of Homo erectus. From the neck down, the creatures resembled present-day people: They had modern stature and body proportions, distinguished by relatively long legs and short arms.
What are the three types of humans?
Fast-forward to 300,000 years ago and the H. erectus lineage gave rise to at least three varieties of humans: European-based Neanderthals, Denisovans in Asia and the ancestors of all living people, Homo sapiens in Africa. The intervening span is what anthropologists call “the muddle in the middle”.
How many years ago did Homo sapiens live?
Over 1 million years ago our ancestors belonged to the primitive-looking species Homo erectus. Jump to 300,000 years ago and Earth is home to at least three lineages of big-brained humans: Homo sapiens, Neanderthals and Denisovans. So what happened in the intervening 700,000 years?
What is the oldest DNA ever recovered?
That timeline agrees with a 2016 genomic analysis of the ~430,000 year old Sima fossils — the oldest human ancient DNA yet recovered. The sequences suggest the individuals belonged to the Neanderthal lineage after it split from Denisovans. It’s safe to classify the Sima hominins as Neanderthal ancestors.
Which fossils are used in the Eurasian fossils?
Proponents of this hypothesis often draw the division between African and Eurasian fossils. They use Homo heidelbergensis for Eurasian fossils leading to Neanderthals and Denisovans, and Homo rhodesiensis for Mid-Pleistocene African hominins likely on the lineage leading to modern humans.
How much of the Sima genome was recovered?
The scientists salvaged just 0.1 percent of the Sima genome from one bone and tooth.
