When “DARWIN” passes by…. !!

When “DARWIN” goes through there with his theory of evolution, it gives us a breath of fresh air for the future and a good lesson to the primates that we are who are bent on destroying this fish appeared 400 million d years on earth, showing us its adaptability and that it will still be there long after man has disappeared!

"Hybrid sharks discovered off Australia"

Scientists said on Tuesday they had discovered the world's first hybrid sharks in Australian waters, a likely sign, they say, that these predators are adapting to climate change. The cross-breeding of the Australian black tip shark, found near the coast of this country, to that of the black tip found elsewhere in the world, has implications for all of these animals, said researcher Jess Morgan, from the University of Queensland. “It was very surprising because no one has seen a hybrid shark before. It's not something you can easily imagine, ”he told AFP. "It's evolution live." Scientists have studied 57 specimens of these hybrid sharks. Researchers were doing work off the east coast of Australia to inventory wildlife when genetic testing showed that some sharks belonged to one species while having the physical characteristics of another.

The first results of the study suggest that hybrids are robust and able to reproduce, added Colin Simpfendorfer, of James Cook University, who participated in the research. The Australian black tip shark is smaller than its more common cousin and can only live in tropical waters. On the other hand, his hybrid descendants were found at 2.000km to the south, in much colder waters. By breeding with the common species, the Australian shark is increasing its natural habitat, said Jess Morgan. "This allows species restricted to tropical waters to live in more temperate waters," he added.

If the hybrid specimens prove to be more robust than their "purebred" parents, they could gradually replace them, added Colin Simpfendorfer. “I don't know if that's the case here, but we do know that they are viable, that they reproduce and that there are several generations of hybrids,” he said. "They appear to be quite healthy animals."

These hybrid sharks were numerous, representing in some places up to 20% of the total population of black tip sharks living near Australian coasts. But they do not seem at the moment to cause a drop in the population of their purebred parents, noted Jess Morgan.
