• Biological evolution accounts for diversity over long periods of time.
• Traits that are advantageous often persist in a population.
• Populations evolve.
• Speciation is the splitting of one ancestral lineage into two or more descendant lineages.
• Speciation requires reproductive isolation.
• Occupying new environments can provide new selection pressures and new opportunities, leading to speciation.
• Scientists pose, test, and revise multiple hypotheses to explain what they observe.
• Scientists use only natural causes to explain natural phenomena.
• Scientific ideas are developed through reasoning.
• Science does not prove or conclude; science is always a work in progress.
• In explaining phenomena, the parsimonious claim has the advantage.
• The story 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.
• Scientists use anatomical evidence to infer the relatedness of taxa.
• Scientists use the geographic distribution of fossils and living things to learn about the history of life.
• Scientists use experimental evidence to study evolutionary processes.
• Classification is based on evolutionary relationships.
• Evolutionary trees (e.g., phylogenies or cladograms) are built from multiple lines of evidence.
