Homo erectus went extinct only 50,000 years ago (100,000 tops)
Complete, 100% complete, chromosomes (Y chromosome) of Homo Erectus is assumed to be found in over 9 living Negro human specimens in Cameroon

A00a-L1149 (or A00a1) Y DNA is 350,000 years old in many Negroes. Negroes DO NOT have common ancestor human Y DNA nicknamed "Y-chromosomal Adam" but they keep changing the definition every 5 years, to not let Negroes feel bad :

US Gov scientists agree that some Negroes discovered to be non-human, and Negroes interbred with ape-like creatures long long ago :

"Homo Sapiens sapiens" [note the extra sapiens] evolved outside Africa, and 350,000 years ago entered africa. DNA of Cromagnon in Southern Italy 28,000 years ago has intact modern real human DNA, thus real humans have Cro Magnon and Neanderthal (or Denisovian) DNA.
Homo erectus went extinct only 50,000 years ago (100,000 tops) and was provably low IQ and PROVEN LAZY, similar to current Blacks, but unknown how much DNA admixture of Homo erectus or H. naledi, is in the modern negro, if any, due to heat damage of artifact DNA, Negroes diverged from all real humans 350,000 years ago, as proven and mentioned frequently already (current Negro Y-DNA A00a-L1149 is 350,000 years old!).
Laziness in Homo erectus proof YES LAZY BLACKS! :

Even though Blacks are now proven from over 350,000 years ago, vs real Humans nowadays, There were MANY types of Hominids that looked like humans, right up until each were killed off and replaced by Modern Humans.
TL/DR: Black African negroids are not real humans. Not only do they share too much DNA with chimps, Y chromosome A00a-L1149 from 350,000 years ago is in a few living negros, and though Homo erectus DNA has not been sequenced yet, it is the leading hominid contender for much of the African DNA, and Y chromosome A00a-L1149 origin
