Why European White Hominid Species Follow Behind Hybrid People to The West.

In Eurasia, interbreeding between Neanderthals and Homo Erectus modern humans took place several times. The introgression events into modern humans are estimated to have happened about 47,000–65,000 years ago with Neanderthals and about 44,000–54,000 years ago with Denisovans.

Did Neanderthals mate with erectus? Yes.

The researchers say this is evidence of "strong gene flow” between Neanderthals and early modern humans – they were interbreeding rather a lot. So often, in fact, that as Neanderthal numbers dwindled towards the end of their existence, their Y chromosomes may have , and been replaced entirely with our own.

What changes occurred on the part of introgression, between the Hominid Species and the Wise Sapiens.  Investigation into the crash of two  opposing taxonomic species class.  

What is taxonomy based on?

Taxonomy is the method we use to identify and group organisms based on their similar morphological (physical) characteristics. It is founded on the concept that morphological similarities descend from a common evolutionary ancestor.  Morphology: the study of the forms of things in BIOLOGY; the branch of biology that deals with the form of living organisms, and with relationships between their structures.

***How is taxonomy determined?

Using morphological, behavioural, genetic and biochemical observations, taxonomists identify, describe and arrange species into classifications, including those that are new to science.J
