Do you think there any homos besides homo sapiens left?

Excavations on the Indonesian island of Flores over the last several years have revealed the remains of a type of human, now called Homo floriensis ("Flores Man"). It seems that Flores Man lived as recently as 10,000 years ago.

That's some time ago, but it is still a lot closer to us than any of the other non-sapiens species of genus Homo, such as the Neanderthals.

Exactly why Homo floriensis died out is an open question. Flores has been inhabited by modern humans for at least 2,000 years, probably longer - whether there was any ever contact between the 2 species is unknown.

It's possible that in future we might discover the remains of other species of Homo. But it is extremely unlikely we will find any living populations. Even very remote islands like the Andaman Islands have been populated by modern humans for a long time; and to remain viable a population will need at least a couple of hundred members - very hard to conceal in this age of Google Maps etc.

Hope it helps.

No chance. Every part of the Earth has been completely explored multiple times. Explorers, anthropologists, archaelogists, oil company engineers, etc.

I don't know why not. Islands would be unlikely, though, unless they were locations originally connnected to Asia by land bridges.
