Thanks to their tendency to live among toxin-producing bacteria and to eat plant matter that might hold toxic substances, roaches were "pre-adapted" to the insecticides that humans throw at them, Schal said.

How much DNA do we share with roaches?

In general, however, the overall conclusion is that most genes would share about 98.5 percent similarity. The actual protein sequences encoded by these genes would then typically be slightly more similar to one another, because many of the mutations in the DNA are "silent" and are not reflected in the protein sequence.

Are cockroaches blind?

Though they look nothing like ours, roaches do have eyes. Although many parts of a cockroach's anatomy are fairly primitive, their eyes are quite advanced, giving them almost 360-degree vision of the world around them.

Why do roaches go in circles?

Should you squish a cockroach?

We've recently heard a rumor that squishing a cockroach is a bad idea because it could spread the insect's eggs around, making more baby cockroaches. "The crushing in itself doesn't really spread eggs," said Louis Sorkin, a scientist in the entomology department at the American Museum of Natural History.

Some cockroaches will even eat other cockroaches. Oriental and German cockroaches eat the carcasses of their dead. Some are known to eat cockroach eggs and nymphs if food sources are scarce. Some female American cockroaches will kill and eat their mates.

Do cockroaches send out scouts?
