Learner tasks

Compare one generation of change to several rounds of selective choice.
Track which visible differences appear first and which accumulate over time.
Use screenshots or saved states to support before-and-after discussion.

Learner tasks

Choose one lineage and describe which visible traits changed first.
Compare two different branches from the same starting form.
Explain how constraints and available variation shape what can evolve.

Core Question

How can small heritable changes accumulate into visibly different forms under repeated selection?

Scientific Virtues

Habits to practice

State clearly what the model demonstrates and what it does not claim about real biological systems.
Use repeated runs and comparisons as evidence instead of relying on a single striking outcome.
Treat model limitations as part of the explanation, not as an afterthought.
