5. Although the specimens of Au. Afarensis indicated that Lucy's jaw was rather unlike other hominins, having a more gorilla-like appearance, “Lucy's pelvis and leg bones clearly show that Au. Afarensis walked as erect as you and I”; also Lucy’s pelvic structure indicates bipedal posture; 6. One of the modern tool is the molecular evolution.
Like all other species apes are notorious for grooming another and spend a lot of time grooming one another. Having no tails seem to be a disadvantage, but having longer arms allows them to knuckle walk and swing from tree to with ease. Some apes featured in the film were Chimpanzees and Bonobo apes. Within all those species similarities and differences are common throughout species. No matter how different primates look they all share some characteristics that connect us together by some sort.
The Spider monkey is the most interesting species of the third grade of primates due to, well keep reading. They originate from rain forest and mountain forest of Central and North America (PIN). These monkeys are named for their long arms, tails and legs. The spider monkey moves through trees with great skill and are able to use their tail as an extra lim. The tail is used in almost every move they make, climbing trees, grasping branches, balancing and even protecting themselves from predators.
Drumming is one was chimps communicate with each other. Another is vocal sounds that chimps often make to each other. Chimpanzees make these noises that might sound like nothing to the untrained ear but to other chimps it could be a sign of power or warning one another of danger. Also in the wild chimps often physically communicate with each other. One way is running around, swinging in trees, and making sounds.
This hardening of the teeth would allow them to bite into other animals. Teeth are key to survival, because without food one would die, so the idea behind having teeth is to eat other animals. Shubin also stated the idea that embryos look very similar during development of an organism, no matter how different the limbs developing may be. It was found that a gene known as the Hox gene determines the basic structure and orientation in any given organism, which in the end is how embryos can appear similar. Other features Shubin said evolved are the abilities of sight, smelling, and hearing.
The ape-like molar teeth of Procoptodon were brachyodont (low-crowned) and tended to develop additional longitudinal enamel folds. Tim Flannery has compared them to the molars of the huge australopithecine
In contrast the lower part of her hip was powerfully primitive like an ape adapted for climbing. Tim White and his team inferred from her pelvis that her spine was long and curved like a humans. Ardi’s feet and hands also gave proof that she walked on the ground and climbed in the trees. According to a 2009 article in Science Magazine by C. Owen Lovejoy “Reexaming Human Origins in Light of Ardipithecus ramidus” unlike humans, Ardi had an opposable toe which enabled her to grasp branches and climb in the trees, whereas we have five rigid toes she has one opposable
Other works with monkeys show us they can distinguish between object and subject in a sentence. We presented categories with similarities, but we have others that show us the differences between primates and humans. When we speak about sharing and cooperation, we can see they live in small groups but the difference is humans need their family until he or she can survive all alone. In contrast, the other primates don’t need their family because they have instinct and they learn to eat themselves since they are babies. Last but not least, we can remark differences between both behaviors in the category of mating and leinship.
Journal 3: What similarities in physical characteristics and in social behavior do chimpanzees and bonobos share with humans? Due by the end of week 4 The physical and social similarities that chimpanzees and bonobos share with humans are not vast but voluminous within the similarities that present. For instance, sexual dimorphism is present in all three primates. The shape or size of both male and females are not directly related to reproduction, but are influenced by body size (which is mostly evident with humans and chimps) where the females are smaller than their male counterparts. All three primates have what is called stereoscopic vision, the ability to have depth preception or see things in three dimensional vision.
Primates are extremely social creatures and there is varied diversity in their social organizations – some that have yet to be discovered – which is in large part determined by their adaptation to their environment. These organizations have been broken up into several categories, including dispersed polygyny, bonded pairs, polyandrous clusters, female clusters, and the one male unit, which I will discuss in detail later. In addition to their gregarious social groups, some primates, including Koko, Kanzi, and Chantek have learned to communicate with humans. Dispersed polygyny is common among the nocturnal bushbabies and pottos. These types of primates stealthily hunt for insects, and doing so in groups would be far too difficult.
