Still going on about the ears....
scientific evidence is that an African savanna elephant, an African forest elephant and an Indian elephant are different species. Beyond that they have quite different physical characteristics than simply the size of their ears... that's proof of evolution.
Start looking at the DNA.
You mention sharks... doesn't help your argument. Evolution is driven by species survival. Is there a need for Great White sharks to evolve in some way? You said it: heavier, lighter, able to breach the surface- all attributes acquired to better survive in different environments. And what about the myriad other types of sharks?
I know you will never concede the point. I win arguments by logic and facts with JWs on my doorstep but they simply revert to "faith". Blind faith, I would say.
