- -guided meditation (ex: retreats)-reading saint letters
- -Linnaeus' system-Hutton's statement that the earth was older than previously thought-Lyell's uniformitarianism-Malthus' essay
- -population sizes increase exponentially if all members reproduce -size is normally stable-natural resources are limited-individuals vary (polymorphism)-variation is heritable
- -comparative anatomy-comparative embryology-comparative biochemistry
- A species is organisms' willingness to mate and reproduce fertile offspring in a natural environment
- Russel Wallace; he chose to continue traveling and studying rather than publishing work, which Darwin did, making him more popular and influential
- -homologous structures-analogous structures-vestigial structures
- -non random mating (inbreeding and assertive mating)-mutation-gene flow-sexual reproduction/recombination
- -survival of the fittest-differential reproductive success (the fit have more offspring)-evolutionary adaptation (unequal survival leads to gradual change with favorable characteristics accumulating through time)
- those with a spine vs those without (chordata and non-chordate)
- Inheritance of acquired characteristics (ex: thought that giraffes stretched their necks to reach higher branches, so their offspring then had longer necks)
- -diploidy (we have two alleles for everything)-balanced polymorphism (heterozygote advantage, hybrid vigor, frequency dependent selection)-neutral variation (characteristic that is not selected for or against, like tongue rolling)
- -stabilizing selection-directional selection-disruptive selection-sexual selection
- -reduced hybrid viability (haploids meet, but genetics don't match, so zygote dies)-reduced hybrid fertility (hybrids are generally sterile, ex: ligers or mules)-hybrid breakdown (2nd generation of hybrids is sterile or not as healthy)
- -habitat isolation-behavioral isolation (ex:finch calls)-temporal isolation (ready to mate at the same time)-mechanical isolation (reproductive structures of one don't match with the other)-gametic isolation (egg and sperm don't come together and match)
- - nature vs nurture- stability vs change- continuity vs stages
- Positive correlation (variables go in the same direction) and negative correlation (variables go in opposite directions)
- descriptive statistics (charts and graphs) and inferential statistics (math)
- - developing a theory- hypothesis- research- analyze data and draw conclusions- report findings
- heightened anxieties sharpened debate on immigration in Europe; culture clash; affects belief of freedom of religion; not familiar with democratic ways/burka identification
