Cockroaches Spiders Ants?

Are these Insects the most hardy creatures in the world ? if they could survIve and even flourish during and after the nucular bombing of Hiroshima and Nagasaki when no other creature or plant could.Surely they must be? why do you think they were able to this ?it amazes me and I find it a bit bizarre too

Insects are remarkably hardy creatures; there's evidence of cockroaches in the fossil record dating back at least 300 million years. It's also true that most are extremely industrious. Cockroaches, in particular, are incredibly adaptable; it's reported that they can live in just about any kind of environment and eat almost anything. (They'll even eat the glue out of books - it's a good source of protein). If they lose their head, they can still survive for some weeks. Zoologist, Stephen Tobe from the University of Toronto, however, has disputed the fact that they would survive a nuclear war, although he agrees that they, and other insects, would perhaps survive longer than humans. The reason being that adult insects show very little cell division - the stage at which cell damage from radiation occurs, leading to a greater likelihood of death. But insects would be rendered sterile and eventually die of radiation poisoning.
Reply:It would have to be something in their genetic makeup (DNA) that would allow them to survive.
Reply:Yeah, I know. It is amazing, as are most of the things you learn about animals other than ourselves.

The cockroach is one of the hardiest insects on the planet, capable of living for a month without food. It can also hold its breath for 45 minutes and has the ability to slow down its heart rate.

It is popularly suggested that cockroaches will "inherit the earth" if humanity destroys itself in a nuclear war. Cockroaches do indeed have a much higher radiation resistance than vertebrates, with the lethal dose perhaps 6 to 15 times that for humans. However, they are not exceptionally radiation-resistant compared to other insects, such as the fruit fly .

The cockroach's ability to withstand radiation better than human beings can be explained in terms of the cell cycle. Cells are more vulnerable to effects of radiation when they are dividing. A cockroach's cells divide only once when in its molting cycle, which at most happens weekly. The cells of the cockroach take roughly 48 hours to complete a molting cycle, which would give time enough for radiation to affect it but not all cockroaches would be molting at the same time. This would mean some would be unaffected by the initial radiation and thus survive, at least until the fallout arrived.
Reply:Nothing can survive a nuclear blast, the reason they say cockroaches would survive, is because they suffer no ill effects from exposure to radiation and in a state of nuclear winter they would freeze but not die, allowing them to awaken at the end of the nuclear winter.



again nothing can survive a nuclear blast, the after affects have very little impact on insects.
Reply:no
Reply:they come from prehistoric it is in their d.n.a. to survive ,they can adapted change in any environment to start the chain again.silver fox.
