1.8 to 2.3 million years ago. Homo erectus type specimen is asian,
Homo ergastor and true homo habilis lived in africa from ~2.6 million
to whenever ergastor/erectus evolved, sometime before 1.8 mya it
emigrated from africa either has ergastor/erectus or as habilis. In
the second case genetic exchange must have continued between african
and asia for a considerable time. There appears to have been a second
wave of migration between 1.1 (based on genetics) and .8 kya based on
the evolution of 'heidelbergensis' Petraloma and Ceprano, Dolimo are
examples, the theory is they evolved from bodo/rhodesiensis like
hominids (erectines) into heidelbergensis over a 200 ky period after
which one isolate evolved into neandertals beginning about 250 kya.
