Biology:Leuckart's law
From HandWiki
Leuckart's law is an empirical law in zoology that states that the size of the eye of an animal is related to its maximum speed of movement; fast-moving animals have larger eyes, after allowing for the effects of body mass. The hypothesis dates from 1876,[1] and in older literature is usually referred to as Leuckart's ratio.[2] It was proposed by Rudolf Leuckart in 1876.[3]
The principle was initially applied to birds; it has also been applied to mammals.[4]
Criticism
A study of 88 bird species, published in 2011, found no useful correlation between flight speed and eye size.[5]
