“PBS 3 also describes the leaf-cutting ants of Brazil. They form colonies containing eight million insects, and they cut leaves into pieces and bring them to the nest, but they don’t eat them. Rather, other leafcutter ants mulch them and use the mulch to grow a fungus ‘garden.’ This fungus is used as food for the young leafcutters, which thus depend on the fungus for survival, but the fungus depends on the ants to provide the mulch.
But this fungus garden has a ‘weed,’ a virulent mold that badly hinders the fungal growth. To combat this, some ants have a white waxy coating that is now known to be tangled mats of bacteria that produce antibiotics that kill the mold.
Presumably, by this stage in the series, the producers hope that viewers are so indoctrinated in evolution that they don’t even need to try to produce evidence. To the diehard evolutionist, any phenomenon at all can be adduced as ‘evidence’ for evolution. In this case, they don’t bother to explain how such a complex symbiosis could have evolved, but merely assert that the bacteria and mold are products of an arms race lasting 50 million years.”
