Regarding human evolution I think we need to establish on which continent group apes arise. This will give us our area to generate early Homo and its spread. From that spread we can decide where the sapiens-neanderthalensis-denisova origin is and place our various human species along the migration routes. Then we can decide on where sapiens originates and its spread.
Further to this here are my ideas based on each option.
1) Capricornia-Hatar
Apes evolve in Avarda and spread north and to Rhodin and northern Capricornia.
Homo evolves in either Avarda, Rhodin, or E Capricornia and spreads throughout the continents and nearby islands, excluding the mountains and coldest regions.
The Homo heidelbergensis/rhodesiensis equivalent evolves in Avarda/Rhodin/ECapricornia and spreads to include the mountains and islands. This allows us to put Neanderthal types around the mountains, hobbits on the islands, and others. Ring/chain species could be prominent here.
Homo sapiens then evolves in A/R/EC (probably Rhodin) and spreads to neighbouring continents, merging with the other species in various ways.
2) Ozara-Talamor
Apes evolve in Ozara and spread north to southern Talamor and south.
Homo evolves in either W or E Ozara and spreads throughout the continents and nearby islands, excluding the mountains and coldest regions. Some might make it to Equatoria.
The Homo heidelbergensis/rhodesiensis equivalent evolves near the join of Ozara and Talamor and spreads to include the mountains and islands, including Equatoria. This allows us to put Neanderthal types around the mountains, hobbits on the islands, and others. Equatoria could have a prominent lasting Homo species here.
Homo sapiens then evolves in Ozara and spreads to neighbouring continents, merging with the other species in various ways.
