Locomotion

Owen Lovejoy’s Provisioning had another hypothesis over the arboreal-to-terrestrial shift and the origins of bipedalism. He believed that freeing the early hominins’ hands was very important in starting bipedal locomotion, but not for the reasons Darwin stated. Lovejoy observed that the species between monkeys and apes, males tend to compete for sexual access to females. Female mothers are the ones who take care of Young monkeys or apes without the help of the male father. Female mother’s job is…

specimen is discussed, along with the conditions and context data for each. Then, there is an explanation of how classification was conducted, the cranial and dental anatomy of ARA-VP-6/500 for Ardipithecus ramidus, the post-cranial anatomy and the locomotion type, the comparison of Ardipithecus ramidus and the great apes, hominoid phylogenics and how Ardipithecus ramidus falls in them, and finally a comparison of Ardipithecus ramidus and Australopithecus. The methods and techniques are also…

move gracefully through it's locomotion. This canopy species has adapted to it's tail a lot, to survive in it's area. The underside of its’ prehensile tail is hairless, and has wrinkles which aid in gripping. This primate species as a very specialized adaption of not having a thumb. Their ancestor had an opposable thumb which's size shrunk in size compared to other bones, and now they apparently don't have a thumb, which is very helpful in moving through their locomotion. The Black Spider Monkey…

to cooler toads. This results can e explained by understanding the role of performance in temperature. Cane toads, as many vertebrates, increase their population and expand to new habitats by movement and locomotion (Kearney et al. 2008). The importance of temperature in movement and locomotion relies in the consumption of oxygen, either used in metabolic process when resting (resting oxygen) or used in respiration (maximal oxygen) and blood flow (Seebacher & Franklin 2011). According to…

Miyake et al. (1989) compared Japanese and US-American children’s latency in locomotion towards a toy after their mother’s vocal expression of joy, fear and anger. The reaction time did not differ in conditions for joy and fear. However, reaction time differed in the anger condition with on average .48 seconds before resuming locomotion in the Japanese group and .18 seconds in the American groups. Furthermore, a stop in locomotion was also observed in Hausa children in Africa, when the mother…

of the chip and the technology with them, these fully paralyzed primates on now able to walk, run, jump, and do any sort of maneuvering they please. Scientist leading the study have said that, “This is the first time neurotechnology has restored locomotion in primates.”…

Prior to reading the article, I had never thought much about the external placement, or lack thereof, of the male scrotum. I was sure that it had always been that way, and there was no significant meaning for its placement. However, after reading the article, “The Scrotum is Nuts”, I agree more with the hypothesis of Michael Chance and Roland Frey, “The Galloping Hypothesis”. It is hypothesized that the external placement of the testes was due to the increase abdominal pressure from movement by…

Starfish are classified under the domain Eukarya. Their multicellular presence and existing nuclei exclude them from prokaryotic domains. Furthermore, they are classified in the Animalia kingdom because they are not prokaryotes or protists. Next, Sea Stars fall under echinoderms, which are invertebrates characterized by their hard, spiny skin. The echinoderm phylum consists of mostly sea creatures (Pawson & Miller, 2016). Organisms placed in the Asteroidea class are identified by their arms that…

I am beginning to get far too familiar with rat paws. After thirteen weeks of recording the red-eyed Sprague Dawley rats walking across an elevated horizontal ladder, a circular ladder and a treadmill, I am now tasked with spending my days evaluating the quality of their walking ability. The video begins at an angle below the ladder and the rat appears in the frame. It is roaming around, familiarizing itself with its environment and probably searching for its cage mate. As it moves around the…

was not my first choice but I wanted to show specific boundaries of the enclosure. Orangutans are an arboreal species, because of this I used ropes, platforms, and tree-like structures to create an environment that would be conducive to arboreal locomotion and a forest type environment. For the ground covering, I used a soft moss type material keeping in mind males do…
