Topics about "cognition" include:

  1. Tool use in birds
    What animals can drop stones into a water-filled tube to bring floating food within reach or bend wire to form a hook? Obviously chimpanzees? No, New Caledonian crows have evolved sophisticated tool use too.

Topics containing the search term "cognition" are:

  1. Intelligence and cognition in birds
    House sparrows are known to gain access to shopping malls by flying in front of sensors that operate sliding doors, whilst herons have been shown to be adept fishers using baits and lures.

  2. Dolphin communication, cognition and sociality
    Dolphins are one of the most intriguing sources of evolutionary convergence, having cognitive abilities that seem to find many parallels in the great apes, and rather remarkably even extend to tool use.

  3. Why emit light? The many functions of bioluminescence
    n-a

  4. Bioluminescence
    Flying through the air on a summer's evening or sparkling in the ocean you may see magical flashes of light that signal some of nature's most enchanting creatures, those that are bioluminescent.

  5. Vibrational communication in insects and spiders
    Some spiders have evolved a most remarkable method of capturing other spiders – they imitate the vibrations of insects caught in their victim’s web. And this is only one of numerous intriguing examples of vibrational communication in arthropods…

  6. Electrolocation and electrocommunication in weakly electric fish
    Fish have eyes, but they live in a much more complex sensory world, where even electricity plays a surprising - and convergent - role.

  7. Mimicry in fungi
    Insects pollinating flowers are a familiar sight. But what happens when the "flower" is actually a fungus? Still "pollination", but now it is fungal spores. Read on to learn more about the fungi that mimic flowers...

  8. Echolocation in toothed whales and ground-dwelling mammals
    Given the extraordinary powers of echolocation in bats, it is not surprising that this group has received the most attention. However, they are not the only mammals to have evolved echolocation. Who invented sonar millions of years before the Navy?

  9. Olfaction: insights into convergence
    Although olfaction is very widespread, there is abundant evidence for repeated convergence of key features, strongly suggesting that there really is an optimal solution to detecting smells.

  10. Scanning eyes in molluscs and arthropods
    Some sea snails have a linear retina. What a hopeless arrangement, to see the world through just a narrow slit! Not quite, because they have come up with a rather intriguing trick to extend their visual field - and it's a trick too good to use only once.

  11. Innate and adaptive immune systems
    A vile cough, soaring temperature? When attacked by nasty microbes, our immune system comes in handy. Surprisingly (or not), plants have come up with a very similar solution to dealing with pathogens, but independently...    

  12. Tool use in birds
    What animals can drop stones into a water-filled tube to bring floating food within reach or bend wire to form a hook? Obviously chimpanzees? No, New Caledonian crows have evolved sophisticated tool use too.

  13. Electric fish: insights into convergence
    Ever seen an electric eel in an aquarium? Don’t dare putting your hand in the tank...

  14. Swimming and thermoregulation in sharks and tuna
    Thunniform swimming depends on a large, lunate tail that is joined to the rest of the body via a narrow peduncle. Whilst the tail flicks backwards and forwards, so propelling the animal, the rest of the body hardly moves sideways.

  15. Ants: insights into convergence
    Trap-jaws, silk and agriculture – just a few examples of convergence in the arguably most successful group of insects, the ants…

  16. Camera eyes of cephalopods
    The remarkable similarity between the camera eyes of cephalopods and vertebrates is one of the best-known examples of evolutionary convergence.

  17. Octopus and other cephalopods: convergence with vertebrates
    What could be more different from us than the alien-like octopus? Hold on. Look it in the eye and think again.
