Now what proof do we have that they did come from a sw animal????
Who is to say that there was not always FW rays? and were created at the begining of time?
that pretty much sums up my thoughts on the subjectLBathory;2884126; said:personally, I dont understand the theory behind creationism. I agree that things must have started from somewhere, but how could creatures not have evolved? There is enough proof to show that many, almost all of the animals on earth had prehistoric cousins that went on massive changes through time in order to adapt and thrive on the enviorment that nature gave them. I am a firm believer in the idea that dinosaurs eventually evolved into birds, or at least some species did. and also that humans came from lesser developed beings. We are still evolving.
turkeyboy85;2884131; said:Speaking from my experiance nothing more and thoughts, i dont have any proof to back it up, i remember having a similar conversation about the rays, and someone brought up how the landscape use to be, and the "thought" behind the evolution of the freshwater rays was that they had gotten trapped when the contenents moved and it created a lake, and the salinity started to drop from the rain waters and eventually the lake was then opened up into river systems briinging down the salinity even more so over these thousands/ millions of years.... (I dont have the expertise on this matter to state how long it was) they evolved to not need the salinity.
Where is matt, he can shine some light on the biology portion of the rays
