Give me a break here, Kalt. I wasn’t teaching them that Erectus and Habilis were humans. Obviously Sapiens are human beings. Erectus and Habilis lived alongside each other and evolved differently. But you have no evidence that Homo Sapiens were not evolved from one of these either. We have no clue, there is no evidence period. Could erectus have evolved into sapiens? Of course…That was what I was saying. Erectus evolved into sapiens according to most theorists…And Homo Habilis evolved theoretically into Homo Ergaster which evolved into Erectus, which evolved through some lines into sapiens. So, human ancestry yes, were they exactly humans themselves at that time? No way. .So, yes, I have done my research and don’t fly by the seat of my pants and make things up as I go.

I don’t appreciate the snide comments either about my teaching or the implications that I don’t know my job. I don’t presume to know your vocation or abilities, Kalt, so please don’t make such presumptions with me.
This is what you said earlier -
“But evolutionary theory shows
humans at different levels of evolution living side by side. For example,
Homo Habilis living at the same time as
Homo Erectus.
Homo Sapiens and
Neanderthals also lived at the same time”
As I said, Habilis, Erectus, and Neandertals were not human. If you are telling your students that Habilis is a human at a different level of evolution, you are giving them inaccurate information. They are different species. All species are related.
You later said -
“They were the
early versions of homo sapiens on a ladder of evolution.”
They weren’t early versions of Homo Sapiens, they were
different species. Related, but different. All species are related, but that doesn’t mean that they were early versions of a later, distinct species, as if they were Homo Sapiens 1.0.
Hominid but not human.
If this is the language you are using with your students, they are getting incorrect information.
