Topics about "incisors" include:

  1. Beak structures in reptiles and birds
    Among reptile taxa with beak structures, we find several cases of convergent evolution, for example between turtles, Uromastyx lizards, a number of herbivorous dinosaurs and the tuatara (Sphenodon) of New Zealand.

Topics containing the search term "incisors" are:

  1. Pressure sensitivity and the tactile sense (excluding the lateral line)
    The star-nosed mole is famous for, well, its nose, but do you have any idea what these peculiar 'tentacles' are for? The answer is rather touching and, of course, convergent...

  2. Dental batteries in ceratopsians, hadrosaurs and elephants
    The dental batteries or 'pavements' of ceratopsians and hadrosaurs evolved independently, and yet the dentition of several more distantly related animals also converges on their highly adapted tooth form.

  3. 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. Beak structures in reptiles and birds
    Among reptile taxa with beak structures, we find several cases of convergent evolution, for example between turtles, Uromastyx lizards, a number of herbivorous dinosaurs and the tuatara (Sphenodon) of New Zealand.

  5. Venom and venom fangs in snakes, lizards and synapsids
    Although the evolution of snake fangs itself provides us with a window on convergence, the presence of fang-like teeth in lizards, therapsids and mammals provides an even broader and more remarkable perspective.

  6. Durophagy (hard prey-eating) in fish
    Plenty of animals have an extraordinary capacity to crush hard prey and this has evolved independently many times in the vertebrates. If you suspect it is a durophage, watch your fingers!

  7. Venom in mammals (and other synapsids)
    Beware the venomous shrew! Yes, venomous. And convergent on some formidable lizards...

  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.
