Primates are a group of mammals
including humans, apes, monkeys, lemurs and lorises. The physical adaptations
that all primates share are; a fairly generalized skeletal layout that can be
used for many different modes of locomotion, specialized forelimbs, hands and
feet, a larger brain especially the cerebral cortex, an omnivorous diet, stereoscopic
vision that helps in the perception of depth and measuring distance and a small
number of offspring at birth.
Abiotic means not alive like rocks and soil. Abiotic Factor that affect the zebras in the grasslands is: water
Still trying to figure out the other abiotic factors.
The three major issues that cut across psychology are stability versus change, rationality versus irrationality and nature-nurture issue.
Stability versus change deals with the issue of whether human beings change as they grow older or they remain essentially the same.
Rational versus irrationality illustrates the disparity between a human's mind ability to perceive and interpret correctly or incorrectly.
Nature - nurture issue centered on the relative contribution of genetic inheritance and environmental factors to human development.
They are measures in degrees.
Darwin's proposed mechanism for evolution is natural selection. Natural selection allows species to respond to their surroundings through time, or to become progressively excellently-suited. Natural selection is environmentally based and involves established heritable variation within a population.
They lead to changes in species over time:
- Darwin suggested species will evolve over time, new species originate from pre-existing species, and all species share a common ancestor with each other.
- In this framework each organism has its own special set of heritable i.e genetic variations from the common ancestor that have slowly developed over very longer periods of time.
- Parroted branching activities that isolate new species from a common ancestor create a multi-level tree that connects all living organisms.
