A recent red tide kill in the gulf of mexico , washed ashore a very small snake as this beaded sea snake . Interesting i have just confirmed that they are hear in the united states . possible natural immiagration were there areas are much larger than thought to be existed . perplexing , however a friend that introduced this theorm introduced me to the white pelican often associated with africa . You tube also pointed out other snakes such as annacondas . I have seen one in the water that connects to the gulf of mexico . However with modern transportation customs and immigration people must consider having ships clean from objects that may live aboard such as the european ship rat . that also has been living along the gulf of mexico . noccrutrnal but also a facinating find to say the least . thank you greg and by the way were is my wife .

I refreshed my memory on parallel and convergent evolution. It is somewhat of a continuum, and dropping the term parallel evolution has been cogently suggested. What convergent evolution means is evolution of similar characters, not the result of close relationship. Streamline body form in a tuna and a porpoise is a nice example of convergent evolution in very distantly related organisms. Similarities due to convergent evolution are not evidence of close relationship. Here is a case where biologists have been fooled by convergent evolution into thinking two fairly distantly related snakes were the same species. Hooray for DNA!

scary snakes. I won’t wish to spend a vacation in Australia but I’ll not go near to the beach.

Evolution shouldn’t even be a debate anymore. But convergence has me on the fence. A donky + horse= ass. But asses can’t produce offspring. It’s strange to me that given this trait of these similar species, that it doesn’t hold true with others. Then again; just because that example doesn’t work, others won’t. Need more science to convince me.

Further proof evolution is a lie.

Pitchguest, I disagree. The post is well written, informative, and the research is very interesting.
