Nuclear Cockroaches?!
A final interesting topic to discuss would be cockroaches vs.the bomb", or the notion that roaches would inherit a post nuclear apocalyptic earth from a vaporized human race. Across a population, insects are more robust than mammals in terms of radiation survivability. The reason for this revolves around cell division. Insects and other arthropods growth include molting cycles. As these animals grow larger, they shed their outer skins, or molt. During each molt cockroach cells typically divide once. Cells of any species are most sensitive to radiation damage at the time of their division. Cockroaches molt once per week at most, and the process typically lasts for 2 days. Therefore at any one given time, 3/4 of the cockroach population would not have cells in a state most sensitive to radiation. Humans on the other hand, have blood and immune stem cells that are constantly dividing, making them sensitive to radiation all the time. Not only this, but what would be considered a lethal dose of radiation to a cockroach is many times higher than that of a human. So in comparison to humans, the cockroach would be more durable against a radioactive nuclear catastrophe.
