Topics about "possum" include:

  1. Gliding reptiles
    In the reptiles, different forms of skin membrane (called ‘patagia’) and in some extinct species, primitive feathers, have evolved convergently as adaptations for gliding.

  2. Gliding mammals
    Gliding mammals rely primarily on extensive skin membranes or ‘patagia’ that stretch between fore- and hind-limbs, creating a wing-like structure.

  3. Thanatosis (feigning death) in spiders and insects
    Beetles that "play possum"? A rather interesting example of convergence…

Topics containing the search term "possum" are:

  1. Teiid lizard dentition: convergence with other reptiles, mammals and fish
    Teiids are skink-like lizards whose members show a stunning diversity of tooth types, providing rich evidence of convergence within the teiids themselves, in distantly related reptile groups and even in certain mammals and fish.

  2. Reptile dentition: convergence on complex occlusion
    Some reptiles have transverse chisel-like teeth for slicing, and others have teeth bearing projections ('cusps') that interlock and slice or grind tough food. In each case evolutionary parallels are clear both within and outside the reptiles.

  4. Gliding in feathered reptiles
    A number of reptile species have been discovered in the Mesozoic fossil record, bearing feathers that were apparently used to support gliding locomotion, rather than true, powered flight as we see in present day birds.

  5. Gliding mammals
    Gliding mammals rely primarily on extensive skin membranes or ‘patagia’ that stretch between fore- and hind-limbs, creating a wing-like structure.

  6. Gliding reptiles
    In the reptiles, different forms of skin membrane (called ‘patagia’) and in some extinct species, primitive feathers, have evolved convergently as adaptations for gliding.

  7. Trichromatic vision in mammals
    Who has not enjoyed the splash of colour in a market: gorgeous red peppers, the green of basil and what on earth are these purple vegetables over there? All thanks to trichromatic vision, another story of convergence.

  8. Sabre-toothed cats and marsupials
    Marsupials with giant fangs? Yes, not all of the extinct sabre-toothed cats were actually cats…

  9. Woodpeckers and woodpecker-like birds and mammals
    You think woodpeckers are unique? Consider the ovenbirds. Or even the curious aye-aye.
