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

Kingdom Protista Protist: Eukaryotic organisms (usually unicellular) that is not a fungus‚ plant or animal * 90% are unicellular organisms * Split based on locomotion * The kingdom divides into three main sections being: animal-like‚ plant-like and fungus-like. 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

targeted ecotourists. The study results reveal that non-consumptive wildlife tourism development in China is still in the early stage and semi-captive wildlife tourism is currently the main form of wildlife tourism development in China‚ especially for primate tourism. Moreover‚ due to misunderstanding the meaning of ecotourism and driven by

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

They move with the help of microscopic hair-like structures called cilia‚ which act like oars to push them through the water. They swim by rotating slowly and changing directions often There is be Two Methods For Locomotion. That They use The Flagellum‚ That Whips Back

and tail undulations when they developed a shortened‚ more rigid body form during the Triassic‚ as an adaptation for armored resistance to attack by predators. However‚ terrestrial body form with a carapace and walking-type limbs precluded aquatic locomotion and was preadapted for different types of propulsion. In the transition to aquatic life‚ the shell underwent minimal modifications. These were a lower more streamlined profile and an expansion of the plastrel lobes as an adaptation for swimming

Modern taxonomy has rearranged the group formerly known as Kingdom Protista‚ separating the different types of organisms into their own candidate Kingdoms. Protists vary in how they obtain energy (autotrophic or heterotrophic) and in their locomotion. Locomotion Movement is achieved by several different methods in the protists.
