A member of the family of humans, Hominidae, which consists of all species on the human side of the last common ancestor—the missing link of humans and living apes; some scientists include the great apes in the superfamily of all apes, the Hominoidea, whose members are called hominoids; ...
For instance, it is known that multiple species of australopithecines and other early Homo species coexisted in the same region of sub-Saharan Northeast Africa about 2 mya. Specifically, H. erectus cohabitated with Homo rudolfensis, H. habilis, and Paranthropus boisei in the area of the ...

In order to understand the evolution of any species, we must first establish its ancestral state: what sort of animal did it evolvefrom? For our lineage, this requires that we try and reconstruct theLast Common Ancestorof humans and chimpanzees (marked "A" in Figure 1). The Human-Chimpanzee...
species in order to consume the nuts’ highly caloric kernel (Boesch and Boesch,1983,1984; Biro et al.,2006; Carvalho et al.,2008,2009). Here, we will focus on studies of stone hammer and anvil use in chimpanzees. Previous studies have proposed that chimpanzee nut-cracking shares ...

Also, geo- graphical and/or behavioural isolation can bring about separate species (even if they are able to pro- duce fertile hybrids when they eventually inter- breed). In fact, this could have been the case with Neanderthals and AMHs. In other words, both groups were geographically and ...
Objectives: The Middle Pleistocene (MP) saw the emergence of new species of hominins: Homo sapiens in Africa, H. neanderthalensis, and possibly Denisovans in Eurasia, whose most recent common ancestor is thought to have lived in Africa around 600 ka ago. However, hominin remains f...
species such asH. sapiensare unlikely to be able to respond to such rapid changes by genetic adaptation alone. Instead, they may have responded plasticly, by utilizing their cognitive abilities to support social learning, with adaptation being primarily cultural40. Although climatic changes and their...
The similarities and differences between nervous systems of various species result from developmental constraints and specific adaptations1–4. Comparative analyses of the prefrontal cortex (PFC), a cerebral cortex region involved in higher-order cogniti
