Answer 1

1. Homo sapiens interbred with b. homo erectus, c. Neanderthals, d. Denisovans.

2. The first primates were the prosimians. The primates actually got separated into anthropoids and prosimians where prosimians were the first to separate out.

3.  Australia becoming isolated early on as Pangea broke apart shows e. origins of monotremes. There is a bit of controversy in this topic as many ecologists believe that monotremes existed even before the pangea broke apart and present day Australia's fauna explains more about split between reptiles and mammals. But on the other hand, monotremes are more to be found in Australia rather than on other continents. So option e is most suitable answer.
