All of evolution is a sliding scale. There is no strict delineation.

I never claimed this was a good piece or true or perfect. That "scientist" was being over the top and purposefully myopic with sources provided, they still only desired to shit on someone else's work and then state I didn't read the methods.

There are no real hard facts for that era of time population wise. It's all estimation based on something. It just depends on how you draw the lines in the sand.

There are no hotdogs, there are no sandwiches. It's all a construct of human applied labels.

But I generally agree. 300k years is a long time.
