Primatology is the study of non-human primates and I find it the most interesting of the four subfields. The study of Primatology focuses on the biological and psychological aspects of non-human primates. Also it looks at the similarities shared between humans and primates. Primatologists focus on studying and conducting research on primates in three main ways; field study‚ laboratory study‚ and through captivity. In captivity‚ they try to replicate natural primate habitat in a controlled captive setting

strategy is characterized by lower quantity of offsprings‚ more care for offsprings‚ longer maturation stage and long lived. Though our evolutionary relatives‚ the chimps‚ are facultative bipeds and can carry food in their hands while using biped locomotion for a short period of time‚ it is very energy consuming. It’s very energy consuming for them because they lacked the pelvic and lower body structure to walk energy efficiently that is present in hominoids with obligated bipedalism. Lovejoy’s hypothesis

Compare and contrast Oligochaetes and Caecilians Oligochaetas are earthworms which belongs to phylum Annelida while Caecilians are amphibians that look like earthworm or snakes belonging to phylum Chordata order Apoda and both have similar appearances. Both classes belongs to Eumetazoa having similar characteristics like organ system level of organization‚ increased cephalisation ‚ bilaterally symmetry‚ triploblastic tissue development and coelomate development. The difference is that Oligochaeta

investigate the two major theories trying to explain why do primates have large brains. Even since the seminar study of Jerison in 1973 it has been acknowledged that primate brains are unusually large for their body size. There are three main groups of theories giving more or less persuasive explanations of the evolution of large brains and high cognitive skills in primates. The first group is a group of social theories‚ postulating that primate cognition is a result of complex social interactions between

Then they are split based on their form of locomotion. * They live in moist environments -> aquatic environments or blood. * Even though they are single-celled‚ they are MUCH larger than Archae and bacteria (refer

Caffeine‚ the stimulant in coffee‚ has been called “the most widely used psychoactive substance on Earth .” Synder‚ Daly and Bruns have recently proposed that caffeine affects behavior by countering the activity in the human brain of a naturally occurring chemical called adenosine. Adenosine normally depresses neuron firing in many areas of the brain. It apparently does this by inhibiting the release of neurotransmitters‚ chemicals that carry nerve impulses from one neuron to the next. Like

Prokaryotes were the first cells; bacteria-like organisms • Descendants belong in two groups: Archaea and Eubacteria Symbiogenesis: process whereby cells of one prokaryotic lineage engulfed‚ but did not digest cells from another prokaryotic lineage. The engulfed cell was eventually reduced to an organelle inside the host cell. Eukaryotic products of symbiogenesis include mitochondria and plastids Primary endosymbiosis: development of organelle by prokaryote engulfed and modified the bacteria
