It would be wonderful if the writer of this article would have spent a little more time trying to get the science correct.
Evolutionary biologists are *NOT* trying to figure out how evolution occurs. They may be trying to work out tiny details, but the mechanisms are known. It is well-known that mutations are random, evolution proceeds by genetic drift, and speciation occurs when a population is split, causing two different groups that genetically drift in two directions and eventually become two different species.
Frankly, I'm disappointed that the editors of ScienceDaily didn't vet this article a little better. Scientific concepts can be simplified without making them inaccurate.
Really? There is zero evidence of one species evolving into another distinct specie. There is evidence, plenty of it, of a family evolving but remaining very similar to the original specie of that family. If you look at bird skeletons you can clearly see the resemblance to dinosaurs. There is no crossover reptile / mammal species. It looks like mammals just "appeared" one day after reptiles and after marine gilled species.
