Neural Modularity Helps Organisms Evolve to Learn New Skills without Forgetting Old Skills

Performance is correlated with sparsity and modularity.
Black dots represent the highest-performing network from each of the 100 experiments from both the PA and P&CC treatments. Both the sparsity (p = 1.08 × 10−16) and modularity (p = 1.19 × 10−5) of networks significantly correlates with their performance. Performance was measured in 80 randomly generated environments (Methods). Significance was calculated by a t-test of the hypothesis that the correlation is zero. Notice that many of the lowest-performing networks are close to the maximum of 150 connections.
