Not sure of the date that the illustration was created, but it misses another important group that seem likely to be important. That group is the Denisovans, identified through their DNA in a cave in Eastern Siberia in 2008. Their identifiable DNA has been found in Asian groups down to the Melanesians in Papua-New Guinea, and recently by scientists at the University of Wollongong, in Australian Native peoples.
Here's a comment from a National Geographic web-site:
Quote: "According to one theory, Neanderthals, Denisovans, and modern humans are all descended from the ancient human Homo heidelbergensis. Between 300,000 to 400,000 years ago, an ancestral group of H. heidelbergensis left Africa and then split shortly after. One branch ventured northwestward into West Asia and Europe and became the Neanderthals. The other branch moved east, becoming Denisovans. By 130,000 years ago, H. heidelbergensis in Africa had become Homo sapiens—our ancestors—who did not begin their own exodus from Africa until about 60,000 years ago.
By comparing the genomes of apes, Denisovans, Neanderthals, and modern humans, scientists hope to identify DNA segments unique to the different groups. Early results already suggest modern humans underwent genetic changes involved with brain function and nervous system development, including ones involved in language development, after splitting from Neanderthals and Denisovans. Identifying and understanding these genetic tweaks could help explain why our species survived and thrived while our close relatives died out."

Personally, I would not regard any explanatory information as the last word on the evolution of humans. What we know is based (usually) on quite fragmentary evidence, and only since genetic sequencing became possible have we been able to identify any discovered remains.
Bit what we know, is sufficient to blow the biblical story out of the picture and reveal the Genesis myths for what they are - one small group of modern humans attempting to explain how they came to be - in other words it a 'foundation myth.'
