Not just a discovery, but also a dogma of evolutionary biology staggering:

It is known that most differences between species occur as a result of changes to existing genes, or the duplication and deletion of genes.

But scientists say this gene emerged fully functional out of non-coding genetic material, previously termed "junk DNA," in a startlingly brief interval of evolutionary time.

Interesting, thanks.
I learned such stuff at school, but at that time we did not know about 'epigenetics' - the influence of the environment in swithch genes on and off, and sometimes even changing them.
This is not Lamarckism though, the giraffe did not grow its neck in a few years, but on a more indirect level it indeed it can change all kinds of attributes, for better adjusting to a changing environment.
