hom*o sapiensevolved from their early hominid predecessors between 200,000 and 300,000 years ago and developed a capacity for language about 50,000 years ago.

    On the second picture of a skull, couldn't the weird shape of it just be from weathering or decomposing?

      It very well could be! As Sal said earlier, much of what we know about history, mainly prehistory, is based on detective work.

      They hunt eachother, and still do. Since Chimpanzees are technically hominids, and have been targeted by human hunters, hominids still hunt each other. However, I assume that you're talking about prehistoric hominids, and the answer to that is that we don't know.

      There is very limited information on interaction between hominid species. Most hominids have a diet largely based on vegetables and scavenging. Active hunting is rare, and hunting other predators is extremely rare. So any conflict between hominids would be rare. Similar, it would be difficult for different hominid species to communicate with eachother, so it's unlikely that they would have cooperated with us. Humans today don't trade with chimpanzees or gorillas largely because of this extremely steep communication barrier.

      However, we do know that Neanderthals and hom*o Sapiens interacted. This is evidenced by the presence of Neanderthal DNA in the genome of people of European, Middle Eastern, and Asian descent. That indicates that there was at least some inbreeding between neanderthals and hom*o sapiens, which suggests intimate relationships between the two groups. Beyond that, the nature of neanderthal-hom*o sapiens interaction is still unclear.

    As our ancestors didn't know how to communicate with each other, and also their brains were in the process of development, then how were they convinced to migrate somewhere else?
    I got this question because they might not be even knowing their purpose on Earth and who those other creatures were.
    I hope my question makes sense.

      Our ancestors did know how to communicate with each other. I believe early primates easily used body language as a start (look at modern primate studies showing complicated body language within species). (Indeed, look at modern hom*o's use of body language). As these primates evolved, they used their increased motor skills and memory to create sign language. Spoken 'language' was often counterproductive as it allowed others (predators) to hear you. Look at the success of modern men who are deaf but communicate easily with sign.
      There are only three truly important things in the life of a primate: food, clothing, shelter. Any one of these would encourage a clever primate to find any or all of these three. Migration is just one response to these needs.
      By the way, have you ever wondered if the migration maps are backwards? Assume the original hom*o line developed in Malaysia. Then the migration direction would be the opposite of the current guesswork direction. Who's to say which way/direction early hom*o wandered?

    2. also if we evolved from chimpanzees why there are still chimpanzees living they all should have evolved ryt ?and there should be no monkeys in th e world

    I think when all the land masses were all together and had not separated hom*o sapiens migrated and whoever was on the continents when they broke up stayed on that continent. They didn't need to voyage great oceans that way.

      It's highly possible that they took advantage of when the landmasses were together, but they definitely crossed the sea to get to Australia. The fauna over there was unique and had evolved in isolation for years.

      Just wanted to elaborate on David Alexander's answer because I love this part of history!
      In regards to Neanderthals there was a relatively long period of co-habitation (as showed by the interbreeding), there is some evidence of small-scale territorial skirmishes but no out and out war between hom*o sapiens and Neanderthals.
      The most plausible theory we have for the extinction of Neanderthals is climate change. Neanderthals went extinct during the Heinrich H5 event (a thousands of years long shift from cold conditions to even colder conditions) There were extinctions of a number of large mammals during this general time.
      hom*o sapiens had better technology and trade networks so they coped better with the changing environment. It is possible they took advantage of the weakened Neanderthal's hunting grounds but so far it's not thought hom*o sapiens caused the extinction of any other human species.
      Here's some articles on the subject:https://www.bbc.com/news/science-environment-60305218 and https://www.sciencealert.com/did-humans-wipe-out-neanderthals-it-s-complicated

      The Bering land bridge theory has not been debunked. It is still the most widely accepted and feasible migration route.
      But as you pointed out there are a few other ideas that have been put forward in recent years, mainly hypothesizing that humans migrated to the Americas via boats and coastal travel.

      These are good theories but they are based off small localized studies and have not yet been properly tested. I cannot find anything about tools being found that predate the land bridge, only that their structure and style is earlier and slightly outdated but that could be due to other factors such as materials used or function.
      It is wrong to say the Bering land bridge is false, perhaps one day one of the new hypotheses will be proven but so far...it's the land bridge.

      Side note, I have heard that some First Nation peoples and tribes disagree with the Bering Land bridge theory on a spiritual level as they believe they originated in the Americas rather than in a foreign country.

      I hope this cleared up some stuff, if I missed something please link it below I'm always open to new info :)
