If you could travel back to Spain about ten million years ago, you'd have no end of animals to watch, what is meant by the term relationship centred working apes to bear-dogs to saber-tooth tigers. With so many creatures jockeying for your attention and perhaps chasing you down for lunchyou might well miss the creature shown here.

What are pandas prey and predators batalleri was roughly the size and shape of a puma, although its face looked more like a raccoon's. If anything were to draw your attention to Simocyonit would probably be the animal's gift for climbing trees. Most big carnivorous mammals of the time were restricted to the ground; some may have been able to climb up tree trunks and onto bigger boughs. But judging from its fossils, Simocyon could have climbed trees out to what are pandas prey and predators slender branches.

It could do so because, unlike other carnivores, it had thumbs that it could use to grasp branches much like a monkey would. Those thumbs turn out to have a fascinating story to tell about the tinkering habits of evolution. This story is a sequel of sorts. If you haven't what are pandas prey and predators it, you really should check it out, either in Gould's collection of essays, The Panda's Thumbor here.

And also be sure to read the blog of the same name! In the essay, Gould complained that textbooks liked to illustrate evolution with examples of optimal design, such as insects that exquisitely mimicked a dead leaf. Darwin himself spent a lot of effort uncovering the strange contortions by which organs changes shape and took on new functions. And to Gould, the thumb of the giant panda was the epitome of a funny solution. Before a giant panda eats a piece of bamboo--its favorite meal--it grabs the shoot between its flexible thumb and finger and strips off the leaves.

But this useful thumb is not what are pandas prey and predators a thumb at all, at least in our sense of the word. Pandas descend from dose response relationship in pharmacology slideshare mammal ancestors, as reflected in the many traits they share with bears, dogs, and other relatives. For one thing, its true thumb is lined up with its other fingers.

What looks like its "thumb" is actually a wrist bone the sesamoid that evolved until it was so big that it stuck out to one side of its forepaw. The muscles that control the bone have become rearranged so that now it can move much like our own opposable thumb. Gould pointed out that the corresponding bone in the panda ankle is somewhat oversized, what are pandas prey and predators he suggested was the result of genes that controlled the growth of the sesamoid in all its limbs.

The large size of its ankle bones serve no function. Instead they're merely the byproduct of natural selection acting on other parts of the panda body. I find Gould's essay a little peculiar to reread today. It's as if someone had drawn a picture of the head of a dime, and Gould said, "Outrageous--it's the tail that makes the dime! The wings of different species of bats are exquisitely well adapted to different ecological niches--open spaces, dense forests, and so on. But the biologists who study those wings would not deny that they originated from the forelegs of mammals, or that an entirely different sort of wing might actually do a better job.

But my opinion may be colored by the what are pandas prey and predators that I'm reading the essay in Perhaps what seem like straw men today were genuine points of view in the s. Of course, it's largely thanks to Gould that such overly adaptationist points of view are not so common today. There's an interesting omission to "The Panda's Peculiar Thumb": the red panda. This bushy-tailed creature is the size of a small dog and climbs in trees.

Found in East Asia, it eats bamboo, along with lichen, acorns, and even bird eggs. It earned its name from the similarities it bore to giant pandas. Those similarities include a false thumb that is actually an exaggerated sesamoid bone in the wrist. More detailed studies raised doubts about whether the two pandas were closely related. But for a long time scientists had a difficult time determining their kinship. The picture has cleared up dramatically in the past few years thanks to large-scale studies of mammal DNA.

These studies such as this one and this one indicate that giant pandas and red pandas are only distantly related. Their common ancestor lived 40 million years ago. One lineage gave rise to bears, including giant pandas. Another lineage gave rise to red pandas as well as skunks, raccoons, and weasels. This research casts the panda's thumb in an interesting new light.

It apparently evolved independently in two different lineages of carnivorous mammals. This is fascinating for a couple reasons. Two independently evolved sesamoid thumbs hint that carnivores are so constrained by their anatomy that they have only one pathway by which they can evolve something that will work like an opposable thumb. It's also intriguing what are pandas prey and predators these two thumbed creatures also share a taste for bamboo. That coincidence may suggest that the same ecological shift from meat-eater to bamboo-eater drove the evolution of a bamboo-processing thumb.

It's the sort of hypothesis that evolutionary biologists can test. They test it by digging up fossil relatives of living red pandas or giant what are pandas prey and predators. And now they've found one-- Simocyon batalleri. In a paper that was published on-line this week by the Proceedings of the National Academy of Sciences, a team of paleontologists describe Simocyon batalleriwhich turns out to be an ancient relative of red pandas.

And like living red pandas, it had a thumb made out of a sesamoid bone. But its jaws, teeth, and other traits were not the sort you find in plant-eating mammals. Instead, it hunted or scavenged prey. In the red panda lineage, in other words, the panda's thumb evolved before red pandas began to use it to strip bamboo. The researchers suggest that the thumb may have originally evolved for a different function: grasping branches.

Simocyon may have used this skill to escape from bigger, faster predators. It might have even stolen dead prey cached in trees by saber-toothed cats and retreated out of range. What are pandas prey and predators after the panda's thumb evolved in a tree-climbing predator did some descendants co-opt it forfeeding on bamboo. In this respect, red pandas appear to have taken a different evolutionary path than giant pandas.

No fossil of panda-like bears has shown any trace of a panda's thumb. Unlike the case with red pandas, the evolution of thumbs in giant pandas may have been tied to a shift from meat to plants. Unfortunately, Stephen Jay Gould is not around to take delight in this new discovery he died in I'd wager that he would have been particularly tickled by the fact that red pandas now embody not what does the multiplier effect do but two of the concepts Gould championed in his career.

He argued that evolutionary biologists must always remember that a structure that has one function today how to obtain affiliate links have actually evolved millions of years ago for a different function altogether. Feathers, for example, don't seem to have evolved initially for flight.

Some scientists liked to call these structures preadaptations, but Gould thought that term smacked of some kind of foreknowledge, which evolution cannot have. He preferred the term exaptation. The red panda's thumb turns out to be a striking exaptation--a tool for grasping branches that was turned into a tool for what are pandas prey and predators plants. It's an exaptation we humans can certainly appreciate. After all, our primate ancestors used their opposable thumbs to clamber around branches, perhaps alongside some of the ancient relatives of red pandas.

While red pandas used their opposable thumbs to eat plants, hominids used them to make stone tools. Civilization and all the rest followed suit. Register or Log In. The Magazine Shop.
