Upright walking allowed the human lineage to exploit the expanding territory opened up by the reduction of the forests.  By the time Homo erectus evolved the savanna had greatly expanded while the forests had been greatly reduced, so they had more savanna territory to exploit and their populations did not need to decline with the other apes that relied on the forests.  Homo erectus could exploit both forest and savanna, but in the forests they were in competition with the other great apes.

But we're not speaking of unambiguous erectus and it's found in
association with Paranthropus. And we do find them all the way up
through Eurasia and into Melanesia.
They didn't fly.
They had to submarines.
"Coastal Dispersal."
The followed the waterline, exploiting marine resources and, yes,
periodically pushed inland, settling and adapting...
