It is shown that when \sigma_d < \sigma_b, speciation in the trait space occurs. This is what we reproduce here. ## Running the world ![]() ## Plotting lineages A cool feature of ABMEv.jl is its ability to track agents ancestors traits (cf [Agent section](../manual/agent.md)) On can plot it, to get an idea of the coalescence of the population. ![]() Beautiful, isn't it? !!! tip "Making sense of trait histories" Some metrics are available (cf [Metrics section](../manual/metrics.md)) that summarize the divergence in trait value (or geographical position) through time).
