Homo rhodesiensis
(“Broken Hill Cranium”)
.
dated to either 130,000 years ago (using amino acid racemization determination)
.
or 600,000 to 800,000 years ago (within the same time as Homo erectus),
depending on which dating method is used
.
(“archaic homo sapiens” is a loosely defined term used to describe a number of varieties of homo, as opposed to ‘anatomically modern humans’ (homo sapiens sapiens), in the period beginning 500,000 years ago)
.
(the term is typically taken to include…)
“homo heidelbergensis”
.
“homo rhodesiensis”
.
“homo neanderthalensis”,
.
(and sometimes) “homo antecessor”
.
(a number of varieties of homo are grouped into the broad category of archaic humans in the period beginning 500,000 years ago (or 500ka))
(it typically includes Homo neanderthalensis (40ka-600ka), Homo rhodesiensis (125ka-300ka), Homo heidelbergensis (200ka-600ka), and may also include Homo antecessor (800ka-1200ka))
(this category is contrasted with “anatomically modern humans”, which include Homo sapiens sapiens and the subspecies “Homo sapiens idaltu”)
(“modern humans” are theorized to have evolved from “archaic humans”, who in turn evolved from “homo erectus”)
(varieties of “archaic humans” are sometimes included under the binomial name “Homo sapiens” (Latin: “wise man”) because their brain size is very similar to that of ‘modern humans’)
(‘archaic humans’ had a ‘brain size’ averaging ‘1200’ to ‘1400’ cubic centimeters, which overlaps with the range of ‘modern humans’)
(‘archaics’ are distinguished from ‘anatomically modern humans’ by having a ‘thick skull’, prominent ‘supraorbital ridges’ (‘brow ridges’) and the ‘lack of a prominent chin’)
(“anatomically modern humans” appear from about 200,000 years ago and after 70,000 years ago (see “Toba catastrophe theory”), gradually supplanting the “archaic” human varieties)
(non-modern varieties of Homo are certain to have survived until after 30,000 years ago, and perhaps until as recent as 10,000 years ago)
(which of these, if any, are included under the term “archaic human” is a matter of definition and varies among authors)
(nonetheless, according to recent genetic studies, modern humans may have bred with “at least two groups” of ancient humans: ‘Neanderthals’ and ‘Denisovans’)
(other studies have cast doubt on ‘admixture’ being the source of the shared genetic markers between ‘archaic’ and ‘modern’ humans, pointing to an ancestral origin of the traits originating 500,000 to 800,000 years ago)
(new evidence suggests another group may also have been extant as recently as 11,500 years ago, the Red Deer Cave people of ‘china’)
(‘Chris Stringer’ of the ‘Natural History Museum’ in ‘London’ has suggested that these people could be a result of mating between ‘Denisovans’ and ‘modern humans’)
(other scientists remain skeptical, suggesting that the unique features are within the variations expected for human populations)
.
(archaic homo sapiens had ‘robust skeletons’, indicating that they lived a physically demanding life)
.
(this may mean that ‘anatomically modern humans’ – with their more ‘gracile frames’ – had become more dependent on ‘technology’ than on ‘raw physical power’ to meet the challenges of their environment)
