    Shark hybrid

    Australia's hybrid shark reveals evolution in action

    Hybrid sharks have been discovered swimming in the waters off Australia's east coast. The finding may be driven by climate change, a research team says, suggesting such discoveries could be more common in the future.

    The hybridization is between the Australian black tip shark which favors tropical waters and the larger, common black tip shark, which favors sub-tropical and temperate waters.

    While the distribution for the genetically distinct species overlaps along the northern and eastern Australian coastline, the finding that they mated and produced offspring is unprecedented, according to the discovery team from the University of Queensland.
    "To actually find something like this and prove it genetically is unprecedented," Bob Hueter, director of the Center for Shark Research at the Mote Marine Laboratory in Sarasota, Florida, told me Tuesday.

    Hueter was not involved with the research, though one of the scientists responsible for the discovery used to work in his lab, which he said lends the finding credibility. The finding is based on genetic testing and body measurements and reported December 2011 in the journal Conservation Genetics.

    The team identified 57 of the hybrids from five locations spanning 1,250 miles along the Australian coast.

    Bob Hueter is one of the foremost shark experts in the US. He taught our class on sharks at Mote when I first started. I'm going to try to sit in again when the classes are taught again in February.

    How many miles per gallon that hybrid gets?

    so....a hybrid and proof of evolution is the mating of two subspecies of the same species?

    they know that we've been doing that on purpose for 1000's of years on purpose with both domesticated and wild animals?

    it looks like from that article that they are distinct species that happen to share the same common-name. distict species aren't supposed to be able to produce viable offspring

    How do you explain yourself?

    That's exactly what they were saying in the article.

    While the distribution for the genetically distinct species overlaps along the northern and eastern Australian coastline, the finding that they mated and produced offspring is unprecedented, according to the discovery team from the University of Queensland.

    "To actually find something like this and prove it genetically is unprecedented,"

    Bob Hueter is a serious shark expert. I'll accept his word that it is unprecedented. We had two dolphins that are very rare at Mote. They took great pains that they never bred. Yes, they were both dolphins, both "deep sea" dolphins vs the larger bottlenose dolphins here that live in the shallow bays, but they were enough apart genetically that they either/or could not or should not breed.

    All religions have to face the conundrums within their dogmas sooner or later, no? Why should science be immune?
