Ah, cockroaches. The scummy, skittering, pesky little pests that somehow manage to vanish whenever you flick on the bathroom light. Like Mother Nature's little Batmans. Part of what makes them so hard to control is their resiliency, which is something of a biological marvel. Here are five reasons the humble roach will outlive us all:
1. They can adapt at a scary-fast rate
In the mid-1980s, exterminators began mixing sugary roach-bait with slow-acting poisons intended to spread and wipe out entire nests. It was an effective pest-control strategy, at least at the time. But by 1993 a strange thing happened: The toxins stopped working.
A new study from North Carolina State University may have the answer. New Scientist reports that, according to biologists, the cockroaches had "tweaked their internal chemistry so that glucose tastes bitter to them." Surviving bugs then "passed their aversions on to their descendants, and Darwinian selection made it more common."
In other words, the roaches had evolved in just a few generations.
2. Females don't need males to reproduce
Females can deliver 40 to 60 live offspring per birth. Need proof? Here's a really gross video:

But laying dozens of ghostly vermin isn't their only super-efficient reproductive trait. Females are capable of what scientists term parthenogenetic reproduction, or virgin births. According to the University of Massachusetts' biology department, "The American cockroach is said to be able to produce parthenogenetic offspring under severe conditions when no males are available." Girl roaches, in theory, could run the world.
3. They could probably survive a thermonuclear war...
4. They can hold their breath for a long time
Ever wonder why pesticides are largely ineffective against large batches of roaches? It's partly because of their highly efficient breathing system....
Scientists think the mechanism helps regulate the insect's loss of water, especially during extended dry periods.
5. Yes, they can live without their heads
Here's a no-brainer: If you or I were to have our heads cut off, we'd die. We'd lose our ability to process the most basic bodily functions, like breathing. Plus, we'd quickly bleed to death.
Cockroach physiology is a totally different story. "They don't have a huge network of blood vessels like that of humans, or tiny capillaries that you need a lot of pressure to flow blood through," Joseph Kunkel, a biochemist at the University of Massachusetts Amherst, tells Scientific American. "They have an open circulatory system, which there's much less pressure in." If a roach were decapitated, it would simply continue to breathe through its spiracles, and its neck would seal off and clot so there's no uncontrolled bleeding....
I hope y'all appreciate the irony of my new sig image - - I thought of using it as my avatar, but I couldn't bear to part with my little nose picker

I dream of the day cockroaches take over the world.
I'm calling you out on this one. I know what you dream of taking over the world. . . it's those red and black elm tree bugs.
you mean those box elder bugs that I've been plagued with in the past - - that wouldn't be a dream, that would be a nightmare!

yes you're right. elm trees are a plague in themselves, almost as bad as Russian Olives, the worst breed of trees on the planet. Box Elders are almost as bad as Elm trees, they get very huge and often rotten, and can fall through your roof or take down power lines to boot, and they smell bad. . . . the positively the worst thing about them is their tenants.
Hey, quick, PC finger pointers, better read the last few pages in the thread and make sure you come down heavily on one side only.
I hope the day comes in my lifetime where a human embryo is equal to the human hosting it.
Fetal tissue transplants are actually part of a long-established tradition of using fetal cells in research. For example, the 1954 Nobel Prize for Medicine was awarded for a polio vaccine that was developed from fetal kidney cells. In addition, fetal cells were used in the production of a widely used vaccine for measles....
There are many potential uses for fetal tissue transplants, but the focus to date has been on the treatment of Parkinson’s disease and diabetes.
