QuestionAnswer
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.
