Such similar species so far away from each other.?

Question

OK, evolutionists. I'm not a creationist but there are some facets of evolutionary theory that don't seem to explain certain things. Such as occurances of closely related species with ranges far from each other that can't be explained by continental drift or ice bridges or whatever. Explain, please: northwestern Atlantic
pink shrimp, pandalus borealis, inhabits Georges Bank and the Gulf of Maine. The very closely related northeastern Pacific bay shrimp, pandalus jordani, the coast from northern California to Puget Sound. As there was always thousands of miles of continent between these locations, and the Atlantic was closed up during the Panagea epoch, how did pandalus get to and then evolve in what became the Gulf of Maine?????

(But thank God it did. It's high into shrimping season at this time. Yum! Tum!)

Answer 1

i'm not familiar with the species you named so i can't really give you an asnwer, but I can ask; are you sure that those creatures are really related?

I ask because I've seen MANY examples of creatures that physically look the same but are hardly related at all. Certain marsupials and moles are a classic example of a phenomenon called convergent evolution. Given a similar environment creatures not closely related will often develop similar morphology. When you look at the molecular data though, you can see the difference.

Anyway, again I don't know about your particular examples but keep what i wrote in mind in regards to what is and what isn't related taxonomically.

Answer 2

There is a such thing as convergent evolution also where similar environments produce distantly related species yet physically similar

Answer 3

It only takes a few to establish a new population. They could have swam around before Panama rose up about 2 million years ago.
