The Humans That Lived Before Us

  • Published: 30 January 2019
  • As more and more fossil ancestors have been found, our genus has become more and more inclusive, incorporating more members that look less like us, Homo sapiens. By getting to know these other hominins--the ones who came before us--we can start to answer some big questions about what it essentially means to be human.

                            Mr. Leavell , it depends on how you define “us”. If a modern human can successfully mate with homo erectus, then it becomes a “prehistoric-human-that-can-be-mated with”. If not, then a “proto-human”.

                                          You should really look into what you're talking about first. Because most of what you just said was wrong.
                                          First if all there are plenty of beneficial mutations found in humans. Mutations don't happen by just losing/gaining a chromosome so mutations don't lead to down syndrome.
                                          Also, many women and some men with down syndrome can reproduce. So you really need to look into what you're saying first.

                                          When a child is born with more chromosomes he automatically loses the ability to reproduce because of Down syndrome so if any genetic mutations happened to the apes then they would have not been able to reproduce

                                          genetic mutation, that chromosome pair fused into one in humans
                                          actually yea genetic mutations happen randomly on their own... most easiest evidence for that is comparing children to their parents
                                          there are similarites ofcourse, but are children perfect 100% copy of their parents?

Perhaps some even older dna may be similarly analyzed. I'm not sure what the limits of this would be - e.g. maximum time before too high a fraction of dna has decayed enough to be impossible to recover...

We just haven't found anything yet or they're just hiding it from us

For example the oldest bones found so far is Lucy found in Ethiopia now what if there are bones found about the same age or older but not in Africa? or what if their were other spices about that time that migrated into Africa from somewhere else? Scientists say Neanderthals came out of Africa with denisovans like 2 million years ago. I don't believe it I bet the earliest bones found so far would be cause there 130,000 to 40,000 years old there are older ones I bet still not found yet that might not have Africa dna.

A lot of humans are against "destroying everything", as should be obvious to anybody that thinks about it for more than a second. Wars are often devastating, but most wars are not as bad as they were say multiple decades ago.

Also, Lucy is sometimes called "Dinknesh" in ethiopia, the country where she was discovered. It roughly translates to "you are wonderful".

They are indeed ignorant, by definition. But the desire to believe a literal interpretation of a book does not automatically make one racist.

In many species, animals use tools when they where taught to while animals of the same species don't use tools if they have never seen any specimen of their species do so. It's cultural. What if there were some groups of humans who used tools and some who didn't, living next to each other. Obviousely, the use of tools would spread because it is quite an advantage, but e.g. if the individuals who know how to make tools die without passing their knowledge to the rest of the group, the others would need some time, maybe generations, to figure out by themselfes or again meet groups who have the knowledge and want to share it. However, they'd still be human all the time...
