Species detectives track unseen evolution
...ings go against received wisdom that the insect or reptile
branches of the animal kingdom are more likely to harbour cryptic species, and that these are more likely to be found in the tropics than in temperate regions. Zoologists should therefore consider factoring in a degree of cryptic diversity as a rando...
