Lizards Beat Birds In Intelligence Test

rhettb writes "Reptiles have long been thought to be dim-witted, but a new study in Biology Letters finds that the Puerto Rican anole, a type of lizard, can match birds in intelligence. Using cognitive tests that have been previously used on birds, researchers with Duke University found that the lizards were capable of solving a problem they've never encountered before, remembering the solution in future trials, and even changing techniques when presented with new challenges. In fact, the tiny anoles solved the test with fewer tries than birds."

    The article itself points out that the conclusion is NOT that lizards are smarter than birds, but rather that this particular lizard is extremely smart:

    While the study found unexpected cognitive abilities in the lizards, an expert on bird intelligence, Louis Lefebvre with McGill University, says that the study doesn't necessarily mean lizards are smarter than birds since birds still have larger body-to-brain ratios than reptiles. Instead it may mean that anoles are among the most intelligent of the reptiles.

    This study shows that anole lizards are particularly quick learners when it comes to this type of test (quickly learning under which cap the food is located).

    I don't think that speed of learning is necessarily definitely correlated to capacity for learning; it's possible that a parrot might learn more slowly than this lizard, but might still eventually be able to achieve more extensive and higher levels of cognitive processing.

    Certain birds (parrots in particular) actually have the capability to count; have object permanence (understanding that an object still exists even when it is out of range of senses such as sight/smell/etc); have self-awareness (understanding that a mirror is showing an image of themselves, not another animal); construct and utilize tools in indirect arrangements (e.g. use one tool to obtain another tool, which is then used to complete a task); learn by observation; and organize in complex social structures with intricate communication. These are all cognitive abilities that are found in early human childhood development.

    That said, this lizard is pretty cool! I kinda want one now...

    Octopus are also very intelligent quiet possible more so then birds.
