There is Cro-Magnid mixed into other groups

It sounds like you said we are only part Cromagnon. Actually we have almost completely Cromagnon DNA with tiny amounts of other species. Cromagnon is scientifically Homo Sapiens, i.e modern humans.

Denisovans were cousins to Neanderthal, both made extinct by us, the Cromagnon, 15,000 to 50,000 years ago. From interbreeding, aborigines in Australia, Phillipines, Melanesia have <5% Denisovan DNA (other Eurasians have smaller traces), Europeans have ~2% Neanderthal DNA.

Erectus is grandpa to all humans. Lived 2 million to 100,000 years ago. No interbreeding from Erectus was discovered in our DNA. Not sure what Australid is.
