What are the challenges that scientists and archaeologists face in the search for the truth on the origin of man.

Beliefs and proof

Explanation:

In my opinion, one of the most hardest challenges that these scientists and Archaeologists face is proof. Is it really the truth? what do i believe? Some believe that humans originated in Africa over 1.9 million and 135,000 years ago. Note the fact 'believe', have scientists proved this theory of evidence? NO. Do they have human witness of how they looked liked? NO.

All around us there are only theories and beliefs but never proof or evidence.

These are some very crucial factors these scientists face, to be able to actually make people think what they think, to try and convince that even though i may not have proof, our studies and reading are 'vastly' true.

Archaeologists main passion is to understand the past, to collect data and readings, to try and interpret hidden meanings... But have we gotten a conclusion? The origin of man is a very complicated subject. As a Christian i have different beliefs, like others will to.

This brings more frustration for scientists and archaeologists to make space for their beliefs too.

I hope this helps and i hope it cleared a bit of confusion, this is just my opinion.

early human migrations are the earliest migrations and expansions of archaic and modern humans across continents and are believed to have begun approximately 2 million years ago with the out of africa migration of homo erectus. this initial migration was followed by other archaic humans including h. heidelbergensis, which lived around 500,000 years ago and was the likely ancestor of both denisovans and neanderthals. early hominids were said to have "crossed land bridges that were eventually covered in water" .

within africa, homo sapiens dispersed around the time of its speciation, roughly 300,000 years ago.the "recent african origin" paradigm suggests that the anatomically modern humans outside of africa descend from a population of homo sapiens migrating from east africa roughly 70,000 years ago and spreading along the southern coast of asia and to oceania before 50,000 years ago. modern humans spread across europe about 40,000 years ago.

the migrating modern human populations are known to have interbred with local varieties of archaic humans, so that contemporary human populations are descended in small part (below 10% contribution) from regional varieties of archaic humans.

after the last glacial maximum, north eurasian populations migrated to the americas about 20,000 years ago. northern eurasia was peopled after 12,000 years ago, in the beginning holocene. arctic canada and greenland were reached by the paleo-eskimo expansion around 4,000 years ago. finally, polynesia was peopled after 2,000 years ago, by the austronesian expansion.
