Evolution, Ancestry & Biodiversity — Chapter overview · Life Science: Biology, Grade 10
Explain population change and branching ancestry using independent evidence.
Chapter question
How do heritable differences and changing conditions shape populations over generations?
Units in this chapter
- Unit 7.1 · Natural Selection
I can explain the four factors — heritable variation, overproduction, competition, and differential survival and reproduction — that together drive natural selection.
- Unit 7.2 · Evidence for Evolution
I can describe how fossils, comparative anatomy, embryology, molecular biology, and biogeography each provide evidence for evolution.
- Unit 7.3 · Speciation & Mechanisms of Evolution
I can describe how mutation, gene flow, genetic drift, and natural selection change the allele frequencies of a population.
- Unit 7.4 · Classification & Biodiversity
I can explain how living things are organized using taxonomy, binomial nomenclature, and the three-domain tree of life.
- Unit 7.5 · Reading Evolutionary Trees
I can identify common ancestry from branching relationships.
