A strain of cockroaches in Europe has evolved to outsmart the
sugar traps used to eradicate them.

American scientists found that the mutant cockroaches had
a "reorganised" sense of taste, making them perceive the
glucose used to coat poisoned bait not as sweet but rather
as bitter.

* There are about 4,600 species of cockroach and fewer
than 30 of these are considered pests.
(There are about 5,400 species of mammals)

* The world's smallest cockroach is only 0.3mm long and
lives in ant nests

* The heaviest cockroach is the huge Australian Rhinoceros
Cockroach at 8cm in length

wow...that's from the website

* no cockroach has ever pretended to have a PhD.

I knew a of cockroach that had a PHD. She was a University trained
Teacher with a University PHD. She lorded it over everyone. Then one
day the State sent me a Teaching Certificate based on Education and Job.
It allowed me to teach in any state school including a State College,
High School, etc.. I didn't spend one minute getting attending the
Teachers classes. Although, if I wanted to teach at a University, I
would have had to fill in the blanks that were left. The laws on
Occupational Teaching are still on the books in many states. It's just
not well known.

At one time, Teachers didn't attend college. They apprenticed to other
teachers. When the Teacher decided you had the necessary qualifications
they either retired and turned it over to you or they recommended you to
another community that needed a Teacher. What's happened is the
University Teachers have snubnosed their way into making everyone
believe that theirs is the only way. It's not.

It almost sounds instead that they *learned* not to eat the poisoned
sugar, which wouldn't be an inherited trait.

Did you watch Fear Factor? They made contestants lie in beds of
Madagascar Hissing Cockroaches - interesting critters. People eat them
too.

Finally, don't forget what the perpetrators of the Rwandan Genocide
called their victims...

So you were watching a roach clip? (You *are* a child of the '60's, now!)

Offspring do not inherit learning. For example, your offspring
will not inherit your math learning, no matter how many math
classes you take.

Son, you have not. Learning is not inherited.
