we think [the two species] have formed some kind of reproductive barrier to each other," Prof Saetre said

Spanish sparrow's religion doesn't allow that. Italian sparrows are the devil!

I'm sure this news will spread like wildfire through the creationist community and make them realize at once that evolution is a fact...NOT!

There has been a few other cases of hybrid animals found over the years. Species which are distinctly different from their two "parent species", but are still able to reproduce. How have these news been met by the creationists? With denial or silence.

Yay, I really enjoy things like speciation and this isn't even island speciation. These birds live in the same habitat environment as their distinctly different Spanish neighbours.

Just wonderful to know that evolutionary principles are alive and well in our world. How unusual and how totally unexpected, hahahahaha. (That was a joke!)

I can't say Aztek, but I am not surprised that creationists can't come up with anything that could remotely answer this:-).

At least, this little bird is a real and recognizable animal. I sort of understood that the creationists couldn't quite come to terms with evolving bacteria and viruses. But this!!! You bet this will throw a spanner in their works.

Pleased am I!!

Creationist spin- See this species was created by hybridization, not natural selection. Darwin obviously didn't know he was talking about. Game over. God done did it.

Evolution continues on through the ages. Fertility with the inability to back cross = new species.

Creationists will no doubt claim they are the same "kind" and in their whizz-dumb with their "advanced" barmy-ology classification system, clearly identify them as the "kind".. ... bird! Possibly even the "sub-kind" - "SMALL bird"!

This can only mean that the Creator still creates!

This is a clear sign of intelligent design! only the Creator could plan this out! what are the odds that two species of sparrows breed and create a viable third species? you should be ashamed of your false pride and your 'research', which is just interference with His plan!!!

Further to my comment @5, this type of new species is well known in plants:

If an allohex-aploid crosses with a diploid an allo-octaploid could arise in a similar fashion, and so on to higher levels of allopolyploidy. An allopolyploid is often intermediate in appearance between both Parental species and cannot reproduce with either. Hence it may merit the status of a new species. Allopolyploidy has been described as instant evolution. -

Many crop plants are believed to have originated in this way. Wheat (Triticum aestivum), for example, is an allohexaploid. It has a chromosome number of 42 and is probably derived from the three species T. monococcum, Aegilops spel-toides, and A. squarrosa, each with 14 chromosomes.

...Also some new garden flowers:-

However if certain of the chromosomes from the two parent species are sufficiently similar (see homoeology) then multivalents may be seen at meiosis. When this occurs the allopolyploids are termed segmental allopolyploids. An example is the allotetraploid Primula kewensis derived from a cross between P. floribunda and P. verticillata.

NCBI paper: No genomic mosaicism in a putative hybrid butterfly species

... However, comparison of our data to DNA sequence data for another putative hybrid Heliconius species, Heliconius heurippa, suggests that the H. heurippa genome may be a mosaic.

In other words, some animal speciations are by allopolyploidy, but others by mosaicism. It is not clear which aplies to this sparrow.

Yes, and don't they realize that barrier devices increase the transmission of disease, apart from what they do to the morals?
