This week in biology we finished the Hardy-Weinberg population genetics lab and started our plant lab on artificial selection. The main focus of the week was speciation.
LECTURE: SPECIATION
- Species: Members who interbreed and make viable offspring
- Morphological: based on appearance
- Ecology: based on niche
- Paleological: based on fossils
- Allopatric: Geographic barriers
- Sympatric: Same area where species evolve for each other
REFLECTION
- Related to big idea number 1
- The process of evolution drives the diversity and unity of life.
- Speciation and extinction have occurred throughout the Earth’s history, speciation may occur when two populations become reproductively isolated from each other, and populations of organisms continue to evolve.
- Speciation happens in nature, but scientists aren’t exactly sure how.
- The idea of slow change over time is more excepted than the idea of rapid change followed by long periods of no change.
QUESTIONS
- How was speciation discovered?
- Can either theory of it be proved?
