There is no controversy that animals, and virtually all life adapt and have changes within the same species. There is however no real examples of a species that is in between or shows any real signs of being in between 2 species. The biggest problem with it all is that life is made of DNA which is basically nothing more than information. You can't get more information added from the same information, you could get different combinations of the same information but you cant get more and different. Single celled forms could reproduce but to also add information? Come on man. Look at the complexity of mapping DNA one error causes horrible results. Evolution proposes that random chance caused millions of versions of life to exist and mutate their dna randomly until a good one sticks and it keeps producing. How many generations would it have taken for the reproductive system to evolve? How many errors would it take for it to completely wipe out all life? Just think about that. When the jump to multiple celled creatures that reproduced sexually happened, the male and female both had to have been evolving at the same rate and both hit it in one generation or the species dies all together.....
Evolution doesn't work like that at all. Evolution is a process that results in heritable changes in a population spread over many generations.
As for how DNA evolved, we're gaining more knowledge every day :
Scientists at The Scripps Research Institute have successfully converted an RNA enzyme (ribozyme) into a DNA enzyme (deoxyribozyme) through a process of accelerated in vitro evolution. The molecular conversion or transfer of both genetic information and catalytic function between these two different genetic systems, which are both based on nucleic acid-like molecules, is exactly what many scientists believe occurred during the very earliest period of earth's existence.

And there are plenty of examples of transitional species, as already posted. There's also endless evidence to show that species on the earth today evolved from species that walked the earth millions of years ago. Here's the latest evidence, made public a few days ago :
In the first analysis of proteins extracted from dinosaur bones, scientists say they have established more firmly than ever that the closest living relatives of the mighty predator Tyrannosaurus rex are modern birds.
The research, being published Friday in the journal Science, yielded the first molecular data confirming the widely held hypothesis of a close dinosaur-bird ancestry, the American scientific team reported. The link was previously suggested by anatomical similarities.
In fact, the scientists said, T. rex shared more of its genetic makeup with ostriches and chickens than with living reptiles, like alligators. On this basis, the research team has redrawn the family tree of major vertebrate groups, assigning the dinosaur a new place in evolutionary relationships.
Similar molecular tests on tissues from the extinct mastodon confirmed its close genetic link to the elephant, as had been suspected from skeletal affinities.

We also have DNA evidence showing evolution in a single species over short periods of time :
Using perfectly preserved, ancient DNA, scientists have demonstrated microevolution in a single species over a span of some 6,000 years. The researchers examined well-preserved bones of Adélie penguins
(Pygoscelis adeliae) found in Antarctica and compared them to the birds' living descendants.
