With or without the dolphin, the fossil evidence for evolution is so strong that it is virtually impossible to refute. It remains a theory, but there are theories and there are theories, based on the amount and the credibility of their evidence. The "theory" of evolution is backed up by a preponderous of such an enormous body of extremely credible evidence that the responsibility for proving their case falls on its detractors.
To my understanding, intra-species evolution is proven, where as inter-species evolution lacks some sufficient proof.
again, inter-species evolution is as certain as the earth revolving around the sun. it doesnt lack sufficient proof. evolution is called a theory in the same sense that gravity is, because people are still learning things about exactly how it works, a scientist that doesnt accept the reality of evolution does not exist. whether evolution is true or not is a dead topic among everyone except lunatics who have no absolutely no clue what they are talking about.
"Inter-species evolution" is a creationist/intelligent design talking point to cloud the issue. Evolution and speciation are two separate things and both processes have abundant evidence. evolution is the change in the genetic traits of a population over successive generations. This is the process that drives speciation. speciation is the evolutionary process by which new biological species arise. It works like a tree with branches forking out into more branches, much like a family tree. It's not like a braided stream with different channels merging again downstream.
Okay... what conclusive evidence is there that humans came from monkeys? To my knowledge, there is only speculation with small bits of evidence...
It appears they are becoming some sort of Bee-Cow. They will have the ability to fly and produce sweetened condensed milk. It is an apples and oranges comparison. The legs on those cows are all in random areas, suggesting a random mutation or conjoining. All dolphins have undeveloped "nubs" in the exact same area. These are just the first to be fully formed. I bet Bee-Cows taste good with some Honey BBQ sauce...
