It all comes dow nto classification.
There’s been a tendency from the late 1980s onward to reclassify many separate homo species back into Homo Erectus.
Homo Egaster was considered the oldest, and from Africa, but now it appears to be part of the Homo Erectus species along with Java Man, except for Homo Heidelbergis, which was given its own distinct species.
The new list of Homo Erectus:
Homo erectus bilzingslebenensis (0.37 Ma)
Homo erectus erectus (Java Man, 1.6–0.5 Ma)
Homo erectus ergaster (1.9–1.4 Ma)
Homo erectus georgicus (1.8–1.6 Ma)
Homo erectus heidelbergensis (0.7–0.3 Ma), now mostly treated as a derived species, H. heidelbergensis.
Homo erectus lantianensis (Lantian Man, 1.6 Ma)
Homo erectus nankinensis (Nanjing Man, 0.6 Ma)
Homo erectus palaeojavanicus (Meganthropus, 1.4–0.9 Ma)
Homo erectus pekinensis (Peking Man, 0.7 Ma)
Homo erectus soloensis (Solo Man, 0.25–0.075 Ma)
Homo erectus tautavelensis (Tautavel Man, 0.45 Ma)
Homo erectus yuanmouensis (Yuanmou Man)
In the history of early Britain below, the earliest settlers were the H. heidelbergensis. (The presenter pronounced the en in heidelbergensis, which is missing in other responses above).
The account maintains that those earliest inhabitants were supplanted by the arrival of H. neanderthalis, who weren't as artful at toolmaking as H. heidelbergensis:

I only recognize 4 names out of 13.
I do recognize “Ergaster” as African, but I did not realize it dates to 1.9 mya, which definitely adds to the mystery of origin.
