Cards

Term
Evolution
Definition
In biology, evolution is change in the genetic material of a population of organisms from one generation to the next. Natural selection has alot to do w/evolution.
Term
3 pts. of Natural selection
Definition

 

  1. a trait must be inherited. 
  2. has to be heritable trait variation. 
  3. fitness relative measure that changes as environment changes.
Term
European World View (Middle Ages)
Definition
Everything, everything was centered around the god, church, and human (nobleman) to a rock Great Chain of Being
Term
Fixity of Species
Definition
God created and therefore life-forms could not change; to genetic change or changes in frequencies of certain traits in populations due to differential reproductive success betweeen individuals.
Term
Great Chain of Being
Definition
is a classical conception of the metaphysical order of the universe in which all beings from the most basic up to the very highest and most perfect being are hierarchically linked to form one interconnected whole.
Term
The fixity of the species
Definition
the species do change but this change is caused by God and therefore is still considered fixity of the species by many progressive creationist.
Term
Hierarchical and Static
Definition
Term
Circumnavigating the Planet and "Discovery" of the New World
Definition
earth no longer flat, as Europeans began to explore they began to see diversity in the human population, plants and animals.
Term
Balanced Tx Acts
Definition
Acts that were passed giving the creationist ways of getting around the constitution.
Term
Creation Science/Intelligent Design Theory
Definition
based on notion that most biological functionsand anatomical traits are too complex to be explained by a theory that doesn't include the presence of a creator or designer.
Term
What is meant by individuals do not evolve; individuals are selected for or against; populations evolve
Definition
important--unit of natural selection is individual; the unit of evolution is population because individuals don't change geneticall, but over time, populations do.
Term
Peppered Moths of Manchester, England
Definition
Light, dark moths and light, dark lichen on trees. The dark lichen is due to pollution and light moths would be eaten by birds, when pollution was improved the light moths did on light trees (no lichen) better in surviving.
Term
Birds are selective agent
Definition
depending on conditions of weather, access to food, will determine survival of one bird species over another.
Term
Ground finches in Galapagos Islands
Definition
  • drought killed many plants that produced smaller, softer seeds favored finches birds.
  • Forced a population of finches on one island to feed on larger, harder seeds.
  • Consequently, were droughts birds whose peaks were larger survived.
Term
Bacteria (disease causing pathogens)
Definition
some bacteria are immune to some antibiotics; some bacterium have inherited resistance and will pass this inherited resistance to new generations and eventually will be drug resistant.
Term
5 pts. Darwin natual selection
Definition
  1. all species are capable producing offspring faster than increasing food supply. Thomas Malthus (no controversy)
  2. there is variation in all species (own observation) (no controversy)
  3. survival of the fitist (Herbert Spencer) Traits give/lesses advantage.
  4. is result of higher fitist (reproduction)
  5. over long periods of time smalll changes--result in big permanent changes
Term
Structure of DNA discovered
Definition
1953
Term
Sources of Variation
Definition
source of all variation must be mutation recombination, immigration of genes.
Term
Blending Theory
Definition
18th century, Europe; parental characteristics were combined to produce intermediate expressions in offspring.
Term
Genome
Definition
entire genetic makeup of an individual or species.
Term
Biological Continuity
Definition
