The comment was:
Funny how cockroaches never EVOLVED in all those millions of years?
No, CRJ, it’s not funny at all. Cockroaches adapted to their environments very efficiently.
Cockroaches are insects, a class of invertebrates within the arthropod phylum; those evolved before the Cambrian explosion, in the oceans.
Today they live in more-or-less all environments on earth. A small number of species of arthropods reside within the oceans today, where their environment is dominated by the arthropod group called the crustaceans.
They have chitinous exoskeletons, a three-part body (head, thorax and abdomen), have three pairs of jointed legs, compound eyes and one pair of antennae. Amongst all the other distinguishing features.
Most existing cockroaches are bigger than their extinct cockroach relatives (roachtoids).
Modern cockroaches belong to the Order Blattraia or Blatteria, which consist of around 4 500 species; only around 30 of them are associated with human habitats and around 4 species are declared pests.
The oldest cockroach-like fossils (‘blattopterons’ or ‘roachoids’) come from the Carboniferous period (354-295 ma). They differ from the modern cockroaches in that they had long external oviposters. Todays cockroaches have internal oviposters . The first fossils of modern cockroaches (with internal ovipositors) appeared in the Early Cretaceous (145 to 100 ma).
Oh, and organisms such as the different species of praying mantids are descendants of a cockroach species.
If you want to read a good book on cockroaches, read Cockroaches: Ecology, behavior and natural history, by Bell, Roth and Nalepa. It would open your eyes to how fantastic those organisms are.
People, please have respect for cockroaches. They adapted to live in far more verified environments that humans can. It just shows that size is not always the best way to ensure survival as cockroaches are much more successful than humans in surviving.
CRJ, your comment was not as clever as you thought it was. It just highlighted your lack of a basic education. Also your disrespect for the work of thousands of people who actually study cockroaches.
Have respect for cockroaches. They are ‘more evolved ’ than you in lots of aspects.
