Homo ergaster Humans.

GeraldtheGnome: 1.8 Million years ago Homo Ergaster Humans first appeared/first evolved in Kenya, the Book I have at home here has it that that was during the Pliocene Epoch (5 mya - roughly 1.6 mya) according to the Author of it, yet whoever put the data about when the Pleistocene Epoch on Wikipedia has it that the Pleistocene Epoch is when this happened 1.8 million years ago. The Book I have is more reliable and more credible, so I'm going by what is in the Book instead. See the topic Homo ergaster on Wikipedia for more information. I will round off the year that the first Homo Ergaster Humans appeared/evolved to 1,798,000 BC, which technically should be considered to be 1,797,999 BC.

OLDOWANS. : There is no proof that one or most or some or 1/2 or all Homo ergaster Humans on Earth back then (even though then they or only one lived in Kenya unless proven otherwise) all had Stone Age/Lower Paleolithic Technology at all as far back as 1,798,000 BC or not. Therefore I will not assume that at least one did and that at least one other didn't if any others did exist then, even if one did maybe one or more did not have any form of technology and that there was or wasn't one or more Homo ergaster Humans that did though.

oatmeal23: Thanks to you i learn something different everyday.

GeraldtheGnome: Thanks.

oatmeal23: ☺

oatmeal23: What makes , i mean what drives you to read and learn such things?

GeraldtheGnome: I want to learn as much as possible, I'm a 'Knowledge Vampire', sometimes my craving for knowledge has gotten me offside with people and in trouble at times.

oatmeal23: Why in truoble? There isn't many like you. That thirst for knowledge.

GeraldtheGnome: Besides learning things keep you going otherwise you'll go stir crazy or arrogant by assuming you know everything.

oatmeal23: True.. i know people like that . Annoying.

GeraldtheGnome: True, but I'm also the 'I don't leave any Stone unturned type' when a crisis happens. Sometimes its better to pretend not to know about something when you find out about certain things.

GeraldtheGnome: Yep, that is true.

oatmeal23: I like learning too , because i think i would go crazy if i stopped... but i dont dive into a book or anything, more like i read articles i stumble upon and your post of course.

oatmeal23: I know what you mean.

GeraldtheGnome: KENYA : HOMO ERGASTER HUMANS. : Homo ergaster Humans may have existed as far back as 1.8 million years ago or thereabouts as suspected by many 'In the Field' but this and even the theory that one or more of them existed in what is now Kenya back then or even 1.75 million years ago has so far not been proven, not even then in any other part of the World. Therefore it can only be safely mentioned that at least only as far back as before or at 1,698,000 BC or 1.7 million years ago or somewhere in between that at least one existed. So far the earliest Human proven to be on Earth then that was a Homo ergaster Human is KNM ER 3733, a Female that lived at what is now Koobi Fora in Kenya.

She so far until proven otherwise was the first of those type of Humans to have appeared/evolved on Earth. There my have been one more others of this type of Human that existed in what is now Kenya and/or outside of it but that so far there is no proof of that. There is also no proof that these types of Humans had a Linguistic or Symbolic way of communicating with each other but some have assumed that they did, including whoever made an entry about that at Wikipedia like it is a fact when it isn't, at least it isn't unless it is proven that it is which I doubt that it has or that it ever will. See the topic KNM ER 3733 on Wikipedia for more information.

OLDOWANS. : There is no proof that Stone Age Technology of the Oldowan kind was used by one or more Homo ergaster Humans during the time of the Lower Paleolithic/ Tertiary Period/Pliocene Epoch as far back as 1,698,000 BC (which is where I squared it off to) in what is now Kenya. If there was more than one of those Humans there then then one or more either had no Stone Age Technology of any kind at all or one or more did have it. The other possibility is that one or more had Stone Age technology then and that there was none of them around that lacked the use of Stone Age Technology. Technically it really should be considered to be 1,697,999 BC. The other confusing bit is the fact that the Author of the Book that I have has it that this Homo ergaster Female classified as KNM ER 3733 lived was around during the time of the Quartenary Period while the person that put the information in about her has it that it happened during the Tertiary Period, once again the Book I have has an Author that is more credible and reliable so I'm going on what he put into the Book instead.
