They crossed at the horn of Africa. When they had to.
Clearly our ancestors were already in Asia more than 3 million
years ago, as demonstrated by the retrovirus data.
The Sahara as we know it came into existence about 5k years
ago, roughly the same time as The Great Barrier Reef -- climate
optimum.
We find what is sometimes described as "Proto erectus" in
Eurasia -- Homo georgicus.
Erectus wasn't in Africa 2.1 million years ago. There is a claim
but that claim is self refuting.

A green corridor through the Sahara emerged
precisely during the period when our earliest
ancestors migrated from Africa. This is shown
by new research from Aarhus University. ...
:-DDD
They *assume* some "migration out-of-Africa",
but there was no such migration!!
some savanna fool:
Despite no fossils there and our closest genetic relatives
and related fossils being in Africa...
:-DDD
How can one be soooo stupid??
1) Fossils:early-Pleist., e.g.
independent indications: Indonesian H.erectus were semi-aquatic
• Archaic Homo's tooth-wear was caused by "sand & oral processing ofmarine mollusks" Towle cs 2022 https://onlinelibrary.wiley.com/doi/10.1002/ajpa.24500
• H.erectus s.s. in coastal sediments, e.g. Mojokerto barnacles +corals, Trinil Pseudodon + Elongaria (edible shellfish), Sangiran-17
• Stephen Munro discovered sea-shell engravings made by H.erectus,Joordens cs 2015 Nature 518:228–231 https://pubmed.ncbi.nlm.nih.gov/25470048/
• Ear exostoses (H.erectus & H.neand.) develop after years of cold waterirrigation https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5696936/
• Pachy-osteo-sclerosis = slow+shallow-diving tetrapods (de Buffrénil cs2010 J.Mamm.Evol.17:101-120), e.g. erectus’ parietal bone is 2x as thick as in gorillas.
• Brain size in erectus (2x apes/australopiths) is facilitated byaquatic foods, e.g. DHA docosahexaenoic acid in shellfish… cf. Odontocetes, Pinnipedia, Enhydra.
• Platycephaly in erectus/neand.: long, flat, dorsally-shiftedbrain-skull = hydrodynamic, google GondwanaTalks Verhaegen English
• Pleistocene Homo colonized islands far oversea, e.g. Flores, Luzonhttps://www.academia.edu/36193382/Coastal_Dispersal_of_Pleistocene_Homo_2018
• Homo’s stone tool use & dexterity is typical for molluscivores, e.g.sea-otters
2) Australopiths were fossil relatives of Gorilla or Pan, of course, notof us, e.g.
M Vaneechoutte cs 2023 Nature Anthrop.1,10007are probably not our ancestors”
“Have we been barking up the wrong ancestral tree? Australopithecines
open access https://www.sciepublish.com/article/pii/94ancestor & upright bipedal humans,
"... australopithecines are not transitional between a semi-erect
but to the contrary, are intermediate between a more upright ancestor &extant semi-erect African apes."
3) Our Pliocene ancestors were NOT even in Africa!contemporaneously by an exogenous source of gamma-RV 3–4 Ma ...
-- Yohn CT cs 2005 PLoS Biol.3:1-11:
"Lineage-Specific Expansions of Retroviral Insertions within the Genome": "ancestral chimpanzee & gorilla spp were infected independently &
human & orangutan populations show no molecular vestiges of this infection"! -- In fact, we knew this for almost half a century:apes that have evolved in Africa from those that have evolved in Asia.
Benveniste RE & Todaro GJ 1976 Nature 261:101:
"Evolution of type C viral genes: evidence for an Asian origin of man":
"A comparison of the viral gene sequences ... distinguishes those OWMs &
Among the apes, only gorilla & chimpanzee seem by these criteria to beAfrican,
gibbon, orang-utan & man are identified as Asian:simply following coasts->rivers.
most of man's evolution has occurred outside Africa."
4) Asian Pleistocene Homo dispersed intercontinentally (Europe & Africa)
5) Many so-called "Homo" fossils (e.g. "naledi", "habilis") wereaustralopiths, not Homo, google e.g.
Concl.:antelopes... :-DDD
only incredible idiots still believe their ancestors ran after
https://nat.au.dk/en/about-the-faculty/news/show/artikel/climate-played-a-crucial-role-in-human-migration-from-africa
:-D These speculations are irrelevant & superfluous:
Pliocene human ancestors were not even in Africa:
Some antelope runner:
How can you leave out habilis, rudolfensis, ergaster, etc
all in Africa?
Who does leaves out what??? :-D
