Primates have been observed to play with sticks, stones and other things in nature. When given human toys, they relish the opportunity to play with them. In a remarkable study conducted by Kim Wallen, a psychologist at Yerkes National Primate Research Center in Atlanta, Georgia, rhesus monkeys ...
Animals are multicellular eukaryotic organisms that belong to the kingdom Animalia. There are many different kinds of animals. There are a few things about them that make them different from other living things: Heterotrophy:Animals are heterotrophic, which means they get the food and energy they ...

The carnivory of hominins is unique among primates in three ways: (1) use of flaked stone tools to access animal resources; (2) acquisition of resources from animals much larger than the hominins themselves (Figure 3); and (3) procurement of animal resources by scavenging. Chimpanzees, our...
which mobilize through RNA-mediated copy-and-paste mechanisms. Among retrotransposons, there are long terminal repeat (LTR) retrotransposon families, including endogenous retrovirus (ERVs), and non-LTR retrotransposon families. We mainly focus on the latter, specifically LINE-1s (L1s), Alus, and SV...
Unbiased readings of fossils are well known to contradict some of the popular molecular groupings among primates,particularly with regard to great apes and tarsiers.The molecular methodologies today are however flawed as they are based on a mistaken theoretical interpretation of the genetic equidistance...
Presumably, the fleshy ancient peaches would have been a desirable food source for large-bodied frugivores such as primates. Of special interest, the fossils show that peaches were already present in SW China before the Pleistocene arrivals of Homo erectus and Homo sapiens29. The universally known...
In the 1860s the French surgeon and anthropologist, Dr Paul Broca, made the remarkable finding that patients who had lost their powers of speech as a result of a stroke (a blood clot in the brain) had paralysis of the right half of their body. He noted that since the left hemisphere ...
The use of porcine cells and organs as a source of xenografts for human patients would vastly increase the donor pool; however, both humans and Old World primates vigorously reject pig tissues due to xenoantibodies that react with the polysaccharide galactose α (1,3) galactose (αGal) present...
