The Selection Pressure Lab

The Selection Pressure Lab Selection Mode Directional Stabilizing Disruptive Environment Drag the red markers to shift the environmental pressure. The shaded area represents the low-fitness zone where mortality is high. The Selection Pressure Lab lets you explore this hands-on instead of only reading about it.

Covers the mechanisms of natural selection and the interactions within ecosystems (Units 7 and 8). It focuses on Natural Selection, Hardy-Weinberg Equilibrium, Phylogeny, Speciation, Population Ecology, Community Ecology from the “Evolution and Systems Interactions” section.

You can drag elements directly on the canvas; the “Next Generation →” button run actions or reset the demo. Every change updates the visualization in real time, so you can see exactly how each variable affects the outcome.

This course explores the fundamental principles of biology through inquiry-based investigations and rigorous scientific reasoning. Students delve into eight core units ranging from molecular chemistry to ecosystem inter… This demo is the interactive piece for the “Evolution and Systems Interactions” section.

You'll build intuition for Natural Selection, Hardy-Weinberg Equilibrium, Phylogeny, Speciation, Population Ecology, Community Ecology — and, crucially, see how they behave when you change the inputs, which is hard to get from a textbook or lecture on Advanced Principles of Biological Systems and Inquiry alone.
