- Present-day species evolved from earlier species; the relatedness of organisms is the result of common ancestry. (LS4.A)
- There is a fit between organisms and their environments, though not always a perfect fit. (LS4.C)
- An organism's features reflect its evolutionary history.
- People selectively breed domesticated plants and animals to produce offspring with preferred characteristics.
- Inherited characteristics affect the likelihood of an organism's survival and reproduction. (LS4.B, LS4.C)
- Scientists can test ideas about events and processes long past, very distant, and not directly observable.
- Our knowledge of the evolution of living things is always being refined as we gather more evidence.
- Our understanding of life through time is based upon multiple lines of evidence.
- Scientists use the similarity of DNA nucleotide sequences to infer the relatedness of taxa. (LS4.A)
- As with other scientific disciplines, evolutionary biology has applications that factor into everyday life.
