| Question | Answer |
|---|---|
| adaptation | A process that intervenes to ensure tht organisms achieve an adjustment to their environment that is beneficial |
| Australopithecus | A prehuman who lived from about 4.5 million to 1 million years ago. Some researchers maintain that this type of prehuman is not a direct ancestor of modern humans but rather is a contemporary of an upright-walking, meat-eating, large-brained species that |
| chromosomes | Carriers of genes,or the hereditary blueprints of organisms. Each human inherits a set of 23 chromosomes frome each parent |
| Cro-Magnon | The closest predecessors or perhaps contemporaries of modern humans, who lived about 35,000 yrs ago. they were expert toolmakers and artists and they lived in tribes that displayed evidence of rules and kinship systems |
| DNA | Deoxyribonucleic acid, A complex biochemical substance that is the basic building block of life. It determines the inheritance of specific traits. |
| estrus | Period of sexual receptivity and ability to conceive |
| evolution | a theory that explains change in living organisms and variation within species. Evolution functions according to processes of natural selection, mutation, genetic drift, gene flow and speciation. |
| gene flow | The movement of genes from one gene pool to another. it results in new combinations of genes in the offspring. |
| gene frequency | The proportion in which the various genes occur in an inbreeding population |
| gene pool | All of the genetic material available to a population to be inherited by the next generations |
| genes | Hereditary units that transmit an individual's traits. They are contained in the chromosomes and made up DNA |
| genetic drift | The fluctuations in frequencies of specific traits in a small, isolated population, so that visible differences between an isolated population and the population from which it broke away become obvious. |
| genetics | the science of heredity |
| genotype | the actual genetic composition of an organism which is not necessarily expressed. |
| hominids | prehuman creatures who walked on two feet |
| Homo erectus | the upright hominid thought to be a direct ancestor of modern humans |
| Homo sapiens | a species whose fossils date back 75,000 years (or perhaps 195,000 years) and includes Neanderthals. The species label for modern humans is homo sapiens sapiens, whose fossils dae back 30,000 years and include Cro-Magnon |
| mutation | A permanent change in genetic material |
| natural selection | a process of evolution in which random traits are tested for their survival value, the successful traits are passed on, while organisms possessing less successful traits eventually become extinct. |
| Neanderthal | A subspecies of Homo sapiens (but some consider them hominids) whose fossil remains date from 70,000 to 35,000 years ago. |
| phenotype | the physical, or outward, appearance of an organism |
| primates | an order of mammals to which monkeys, apes and humans belong. |
| Ramapithecus | A hominoid having hominid-like features,dated between 14 and 8 million years ago. |
| stabilizing selection | When natural selection promotes the status quo rather than change, because change would be detrimental to the organism's adaptation to its environment. |
| Humans exhibit | biological drives |
| Specialized socialization occurs most frequently in | occupational groups or organizations |
| Absence of body contact and stimulation in infants inhibits | development of higher learning functions |
| Which is not an aim of the process of socialization | to teach infants to sit , stand, walk and run in that order |
| The emergence of the self as a result of interaction with others is a common thread in all but of the following theories | behaviorism |
| Darwin's theory lacked an explanation of | how trails were transmitted to offspring. |
| Personality must be considered as | interplay between environment and learned behavior |
| Socialization involves the use of which process to turn a "horde of barbarians" into productive human beings? | symbolic and physical interaction |
| Recent research supports the notion that mother-infant bonding | has biological basis |
| Studies of siblings who shared parents , social class, and everyday experiences have shown that they | view the same experiences differently |
| Successful socialization for humans requires | contact with other humans |
| Natural selection refers to | having a trait or traits useful in a change of environment |
| Cooley's looking glass self refers to | a person's perception as to what others think of him/her |
| The primary agent of socialization is the | family |
| When one knows the roles that one is expected to play and is willing and able to do so, one is | successfully socialized. |
