Evolution — Natural Selection

Evolution unifies biology. Variation within species, competition for resources, selection of best-adapted. Darwin saw finches vary by island. Indirect aim: biology, preparation for genetics, deep time perspective.

• Framework: Montessori
• Unit: Cultural Studies
• Learning area: Zoology
• Level: Ages 9-11

Objectives

• Understand Darwin's theory: variation, competition, selection
• Study finch beak variation
• Connect fossil record to evolution
• Research misconceptions

Materials

• Darwin's Finches illustrations
• Fossil specimens
• Evolution timeline
• Books: Darwin, Gould

Instructions

1. Introduce Darwin's voyage (1831-1836). 2. Galápagos finches: beaks vary by island based on food. 3. Variation exists. Competition exists. Those best adapted reproduce. Trait spreads. 4. Over time: speciation. 5. Fossil record shows lineages. 6. Misconceptions: evolution isn't 'progress'; humans didn't evolve from monkeys (both from common ancestor). 7. DNA evidence confirms. 8. Connect to Second Great Lesson.

Educator tip

Evolution is theory in the scientific sense — well-evidenced framework. Handle religious concerns with respect but clarity.

Assessment

Observe theory understanding, misconception correction, and depth of evidence.
