Bigger dot = bigger body. The map shows what the overlay says; the faint base tint is how fertile the land is.

Population and food

Who eats what

Plant eaters (diet under 0.25), mixed diets, and meat eaters (over 0.75). Predator and prey counts rise and fall together.

Average traits

Trait distribution over time

Time runs left to right and the trait's value runs bottom to top. Brighter = more organisms at that value (each column is scaled to its own busiest value, so you can see its shape). Two bright bands mean two strategies living side by side.

Family tree

Time runs left to right. Each row is a species (a group of organisms with similar genes). A branch's thickness is how many members it has and its color is its average diet (green plants, red meat). A thin line joins a branch to the species it split from, and a red cross marks an extinction. Click a branch to see how it differs from its ancestor.
