Essential Knowledge 1.C.3

Populations of organisms continue to evolve.

Scientific evidence supports the idea that evolution has occurred in all species.

Scientific evidence supports the idea that evolution continues to occur. Illustrative examples include:

• Chemical resistance (mutations for resistance to antibiotics, pesticides, herbicides or chemotherapy drugs in the absence of the chemical)
• Emergent diseases
• Observed directional phenotypic change in a population (Grant’s observations of Darwin’s finches in the Galapagos)
• A eukaryotic example that describes evolution of a structure or process such as heart chambers, limbs, the brain and the immune system.

The student should be able to:

LO 1.25 Describe a model that represents evolution within a population

LO 1.26 Evaluate data sets that illustrate evolution as an ongoing process.
