Study Notes
Understanding Evolutionary Biology
- Natural selection affects individuals, not populations, and leads to change over time in populations and species.
- Natural selection is like gravity, existing without a purpose, and advantageous phenotypes increase an organism's likelihood of survival and reproduction.
- Advantages genotypes and phenotypes change when the environment changes, and new alleles are generated from mutations or gene duplications.
- The theory of evolution does not disprove the creation of plants and animals by a god but provides a plausible alternative.
- Genetic drift, sexual selection, and the movement of genes into or out of a population are key components of microevolutionary change.
- Directional, disruptive, and stabilizing selection are the types of natural selection, each leading to different outcomes in allele frequencies.
- Macro-evolution concerns the evolution of new species and occurs over larger periods of time, with the mechanisms being the same as micro-evolution.
- A species is a population capable of interbreeding, but the species concept poses problems related to reproductive capability, asexual organisms, fossil organisms, geographic locations, and clines.
- Sympatric speciation and allopatric speciation are two forms of species evolution, with the former affecting reproduction by isolating a subset of a population.
- Convergent evolution occurs when two species independently evolve similar adaptations to the same environment, leading to analogous characteristics.
- Co-evolution is where the evolution of one species is strongly influenced by evolutionary changes in another species, such as in predator-prey interactions.
- Gradualism is the idea that evolutionary change happens over long periods of time, while punctuated equilibrium suggests that evolution occurs in rapid bursts separated by long periods of little change.
