New Shrew Has Spine of Steel

sciencehabit writes "It's the size of large rat, but it can reportedly withstand the weight of an adult man standing on its back. Meet the hero shrew, a molelike creature that owes its near-mythological status to a remarkable spine, thickened by extensions of bone that interlock like fingers. The structure was thought to be unique among mammals — until now. An international team of researchers in the village of Baleko, in the Democratic Republic of the Congo, made a surprising find: a slightly different shrew with a similarly 'heroic' backbone. Today in Biology Letters, they introduce Thor's hero shrew (S. thori), named for mammalogist Thorvald Holmes, but invoking the Norse god of strength. The researchers don't yet know how its strength compares to that of S. somereni. After exploring the shrews' swampy palm forests habitat, the researchers also have a new guess about why the spine evolved: They suggest that the creatures might wedge themselves between the trunk of a palm tree and the base of its leaves, then use the strength and flexion of their muscular spine to force open this crevice, revealing insect larvae—a food source that other animals can't access."

    Um, no. The spine did not evolve to meet the needs of the animal, the animal is alive because it had the traits needed to live. This would make much more sense if the statement was that "researchers also have a new guess about why the species thrived while others died."

    The way evolution is presented by most media makes it seem like after a species goes for a few generations it gains some ability like how one can gain a power up in a video game; "Ok... humans make it to the next level... they can either run faster, see further or have faster reflexes.... what will it be?"

    If this animal didn't have the ability to do what it does then it would have probably failed and we would know it now as a collection of bones in some natural history museum instead of a living creature. Now, this is also to say that those with mutations that gave them a stronger spine would be more likely to survive but it's not as if the species had control over the evolution of the spine itself.

The spine did not evolve to meet the needs of the animal, the animal is alive because it had the traits needed to live.

      And how did the animal acquired said traits. Natural selection. By random mutations some animals had traits that provided a slight advantage over others, surviving longer, procreating more often and passing those genes downs where further refinements in the typical life-and-death struggle would reinforce those traits. In the case of this shrews, it started with a slightly stronger back, which throughout generations lead to the unique and amazing spine structures they now posses.

      Your statement is neither more accurate than what the article (and the media) say, nor does it paint a full picture of evolution. Their statements and yours are complimentary. It's a goddamned feedback loop. The animals are alive today because their traits allowed them to survive.

      No, the spine almost certainly did "evolve to meet the needs of the animal". The needs of the animal are to eat and reproduce. The animal eats bugs in the palm fronds. Shrews with strong backbones can move palm fronds further, thus accessing more food. They reproduce better. Wash, rinse, repeat. The eventual result is shrews with amazingly strong backbones. It's unlikely that the strong backbone appeared unprompted, and the shrews then started to move palm fronds.
