Evolution Objective Sheet
Tested Objectives:
Bio 3.4.1 Explain how fossil, biochemical, and anatomical evidence support the theory of evolution.
• Summarize how fossil evidence informs our understanding of the evolution of species and
what can be inferred from this evidence.
• Generalize what biochemical (molecular) similarities tell us about evolution.
• Generalize what shared anatomical structures (homologies) tell us about evolution
Bio.3.4.2
Explain how natural selection influences the changes in species over time.
• Illustrate the role of geographic isolation in speciation.
Develop a cause and effect model for the process of natural selection:
▪ Species have the potential to increase in numbers exponentially.
▪ Populations are genetically variable due to mutations and genetic recombination.
▪ There is a finite supply of resources required for life.
▪ Changing environments select for specific genetic phenotypes.
▪ Those organisms with favorable adaptations survive, reproduce and pass on their alleles.
▪ The accumulation and change in favored alleles leads to changes in species over time.
Essential Vocabulary:
fossil, relative dating, radioactive dating, biochemical evidence, homologous structures, vestigial
structures, embryology, Selection forces, stabilizing/directional/disruptive selection, speciation,
geographic isolation, reproductive isolation, gradualism, punctuated equilibrium, Natural selection,
variation, overproduction, competition, survival of the fittest (best adapted), adaptation, gene pool,
mutations
