Study Notes
- Fossils in a particular stratum provide a glimpse of organisms at that time.
- Adaptations are inherited characteristics that enhance survival and reproduction.
- Natural selection leads to the rich diversity of life we see today.
- Artificial selection breeds individuals with desired traits.
- Evolution of drug-resistant pathogens is an example of natural selection.
- Homology reflects evolutionary history.
- Biogeography explains the geographic distribution of species.
- Species are groups of populations that can interbreed and produce viable offspring.
- Molecular characteristics are used to determine evolutionary relationships.
- Natural selection is one of five mechanisms of evolution.- Evolutionary forces can interact and mutation is the ultimate source of new variation.
- Hardy-Weinberg equilibrium states that the frequencies of alleles and genotypes in a population will remain constant unless acted upon by outside sources.
- Prokaryotes are the most abundant organisms on Earth and are well adapted to a broad range of habitats.
- Members of a group of populations with the potential to interbreed successfully in nature are defined as a biological species.
- Reproductive isolating mechanisms keep gene pools separate and drive separate evolution.
- Hybrid zones can tell us about the process of speciation and its possible outcomes.
- Protists are unicellular, diverse, and important producers in ecological food webs.
- Plants evolved from green algae and have distinctive traits that suggest they are the closest living relatives of plants.
- Nonvascular plants, called bryophytes, do not have an extensive system of vascular tissue.
- Nucleomorphs are organisms that possess residual nuclei and have a genome organized on linear chromosomes.
