    the brains of birds formed by earthquakes or volcanic activity that cause ocean floor bulging are larger than those of their continental closest species, according to a new study. The study suggests that this is due to a series of evolutionary processes on the island rather than differences in the successful settlement of birds.
    new Caledonian crows, Hawaiian crows, and finches are all good at using tools, suggesting that the island may be conducive to the evolution of advanced cognitive function. So far, only two studies have looked at the relative brain size differences between island and continental species -- crows and primates, respectively -- but neither has found any correlation between brain size and island life.
    Sayol of the Spanish Centre for Ecological Research and Forestry Applications (CREAF) and colleagues examined a data set of 11,554 brain-sized samples from 1,931 species of birds (110 species of island birds and 1,821 species of continental birds). In a recent report
    , researchers found that birds living on islands have larger brains than their continental closest species.
    , the researchers believe that the unconscionability of the island's environment leads to natural selection of more brain capacity. Once the island environment deteriorates, the bird's diffusion options are extremely limited, or indirectly forcing individuals to explore and rely on more complex behavioral responses.
