There are contrasts in tool kits used by different groups of chimpanzees, which seem to be a result of the environment in which they live as well as information that is shared by the group. For example, in 1973 it was reported that chimpanzees in Gombe did not use hammer stones, but those of Cape Palmas did. We will explore the tool use of Chimpanzees from the wild, including Gombe, Tai National Forest, and the Congo Basin---and contrast those with Chimpanzees in captivity in locations of Zoo’s both in the United States and abroad.

A recent study by Lonsdorf and collaborators2 was responsible for demonstrating these early sex differences in the light of evolution. The research was carried out with wild infant East African chimpanzees (Pan troglodytes schweinfurthii), at Gombe National Park (Tanzania). Overall, it was shown that young male chimpanzees are more sociable than young females. This has been hard to prove in other surveys. For instance, Brent et al.3 examined whether present or absent siblings affected group affinities of 17 wild young chimpanzees from 6 to 24 months.
Scientist studied chimpanzees in the Nimbia Mountains of Guinea, Africa the chimps were seeing using the rocks and wooden cleavers to break hard nuts into smaller proportions eat. There have been many instances where a scientists have seen chimps use sharp rocks to kill other animals when they’re on the hunt. The rocks are used as defense weapons when they’re under attack and the chimpanzees use male dominance to show who’s responsible. Chimpanzees in the captive have to find new ways to use the tools that are made. Chimpanzees in captivity ... ... middle of paper ... ...ps making tools on the wild.
The gorilla is one of the most fascinating primates known to man, whose evolutionary history has been shrouded in mystery for many years. However, with the advent of DNA sequencing, this great ape’s genealogical history is now coming to light, which is perhaps a contradiction of what was formerly the conventional wisdom of the phylogenetic category of the gorilla. The perception of this great ape was once that of a brutish and aggressive animal, who was to be feared and avoided; yet, through scientific research a newfound understanding of the gorilla was adopted in the mid-nineteenth century. The gorilla has been persistently studied in its natural habitat in the mountain and lowland rainforest regions throughout various parts of Africa, which has enriched mankind’s understanding of this gentle and family oriented creature. Molecular phylogeny was the long held standard for the evolutionary tree of primates and other living creatures; however, DNA sequencing has become the popular and more reliable replacement for this form of classification (Brown, 2002).
Darwin would say that we are fundamentally different from other animals. One assumption was that man was unique from other animals because of the use of tools. However, as noted by Gallup (1979) Jane Goodall discovered that chimpanzees used twigs as tools for reaching food that they could otherwise get to. Chance (2003) states "reinforcement is the procedure of providing consequences for a behavior that increases or maintain the strength of that behavior" (p.141). The chimpanzees had the novel thought of using a twig to reach ants that were inside a tree trunk.
However, zoos and aquariums reflect responsibility to help and promote animal conservation and protection. Without them, many may have never gotten the chance to see exotic animals such as tigers, elephants, or giraffes up close to examine and learn about their nature. Without zoos, almost all of the best observational, behavioral, biological, or genetically based research on several diverse species would have not been possible. And, without zoos and the help of fundamental captive breeding and reintroduction programs with... ... middle of paper ... ...ms, it is humankind's’ responsibility to continue to protect and save the animal kingdom.
