Natural Selection

Description

A visual simulation of natural selection showing a population of bugs on a background. Camouflaged bugs survive while conspicuous bugs are removed by predators. Over three generations the population frequency shifts toward the camouflaged trait, tracked by a live bar chart.

Phases

#	Phase Name	Duration	Description
1	Setup	4s	Title, background (brown/green), initial mixed population appears
2	Generation 1 — Selection	7s	Conspicuous (bright) bugs get crossed out/removed by predator strikes
3	Generation 1 — Bar Chart	4s	Bar chart updates showing ratio shift
4	Generation 2 — Reproduction	5s	Surviving bugs reproduce, new population shown with fewer bright bugs
5	Generation 2 — Selection	5s	Another round of predation removes remaining conspicuous bugs
6	Generation 3 — Bar Chart	4s	Bar chart shows dominance of camouflaged trait
7	Generation 3 — Population	4s	Final population mostly camouflaged bugs
8	Conclusion	4s	Label: "Natural selection favors camouflage"

Notes

• Camouflaged bugs: brown circles matching the background
• Conspicuous bugs: bright red/orange circles
• Predator strike: red X animation over the bug, then bug fades
• Bar chart uses Rectangle objects that grow with ValueTracker
• Three generations clearly labeled
