This program reviews the monitor lizard genus which, dispute the incredible diversity between species, share common traits such as the ability to count, that lead biologists to peg them as the most evolutionarily advanced of the lizards.

Program concludes with the customary, trite comment on human impact on climate change and the environment.—David Foss
