The results of the pre-test demonstrate that apes possessed an accurate memory for the location of the food, that is, they were as accurate at remembering where an item was hidden after 24 h as they were after 2 min.
On the contrary, extant apes possess relatively long hands with a short thumb, in which the musculature is poorly developed [1] [2], [5].
In each of these, great apes possess rudimentary abilities.
Monkeys and apes possess many of the faculties that underlie language.
Dolphins, along with human beings and great apes, possess von Economo neurons that enable them to stay attuned to the ever-shifting nuances of social interplay.
Another possibility is that apes possessed some causal knowledge but it could not be expressed because it was tied to particular actions as it has been shown in previous studies (e.g. Girndt et al. in press).
They resemble what would be expected in the common ancestor of humans and apes in that they possess a mix of human and ape traits.
Additional studies of the pelvis, hand, foot, and skull revealed that A. sediba not only shared a number of characteristics with apes and modern humans but also possessed a number of unique features.
First came the discovery of "Lucy" (Johanson et al. 1982), a 3.2-million-year-old (Ma) Australopithecus afarensis skeleton that was very ape-like above the neck but possessed a suite of characters related to bipedalism throughout the rest of the skeleton.
Gorillas, being the most terrestrial great apes and displaying relatively short and skillful hands with relatively long thumbs, possess a somewhat flatter PDP than the other great apes (Figures 2 3).
Although great apes are popular, charismatic species, we still do not possess a complete understanding of their distribution and abundance, which hinders their long-term protection.
