Explanation / Answer

1. d
The fossil remains of Miocene hominoids are found mostly from Africa, Asia and Europe. Turkey is part of Asian continent.
2. a
Hominins is a group that includes all our immediate ancestors that arose after the split from the chimpanzees.
3. d
Bipedalism allowed hominids to free their arms completely and thus enabling them to make tools, use these tools, carry objects, stretch arms for fruits etc. Walking on two limbs was also more energy efficient and also allowed them to see further.
4. d
Homo is the genus name. Homo erectus is one of the hominins to be found outside Africa. erectus is however the species but Homo is the genus.
5. d
Although Homo erectus differs from both early Homo and Homo sapiens in many different aspects, however the most obvious feature is the brain size or the cranial size.
Brain size of Early Homo = ~500cc
Brain size of Homo erectus = ~ 900cc
Brain size of Homo sapiens = ~1300cc
6. d
7. c
