Species don't "spring into existence". They merge into a new species from an earlier species very gradually over millions of years. You've been reading Creationist sites again. Stop it and read what evolution actually says. The pelican hasn't changed much in 30 million years because no environmental reason has occurred to force it to change. Environmental change drives evolution. Same way Great White sharks haven't changed over millions of years. They evolved into the perfect eating machine long ago. A huge change in the ocean environment would now be required to force them to adapt and evolve to cope.
