The Bayesian beta-binomial model showing termites substitute wood with clay.

for the ‘With Load’ units of (a) the field experiment and (b) the laboratory experiment. The evolution of the beta-binomial distribution over increasing number of replicates (from light to dark green, then light to dark blue, to black) shows the median probability of termites substituting wood through clay. The insert shows the 99% Credibility Interval at the highest density region
