I take it that you've never heard of Culex molestus. In the 1860s, members of the London mosquito population migrated into the newly constructed Underground. Their isolated environment forced them to change feeding and mating tactics. C. pipiens, the surface species, rarely bites humans, instead focusing on animals. The underground species, dubbed Culex molestus, only bites humans. It also follows radically different breeding patterns.No, that's incorrect. False taxonomy. Still C. pipiens; or has always been a distinct species. C. molestus has been determined to be a new species. It cannot successfully interbreed with C. pipiens Based on what observation? Contrary to what scientists claim, the London Underground is not an isolated environment at all. Mosquitoes are actually more free to enter and leave than humans are! BTW . . . you sure that this species isn't really Culex Molestus from Australia? The British Empire extended that far and certainly could have carried these with them on their famous merchant navy. Contrary to your claim, there have been many such observed instances of speciation Name one where one creature turns into another. This is one of the linchpins upon which the theory of evolution hangs. Not to mention the fact that viruses/bacteria often mutate and adapt themselves into new niches. The HIV virus is a prime example of this: The virus that causes AIDS is very different than the chimpanzee-specific virus. Looking at criteria for differentiating asexually-reproducing species, it's clear that viruses and bacteria have generated many new species No, they've generated new individuals. There isn't enough variety among such creatures to determine species; nor has any such species turned into a so-called higher form of life. |
