Evolution
A mitochondrial genome phylogenetic study suggested that anglerfishes diversified in a short period of the early to mid Cretaceous, between 130 and 100 million years ago.
Ranging in color from dark gray to dark brown, these carnivores have huge heads with enormous crescent-shaped mouth filled with long, fang-like teeth angled inward for efficient prey grabbing. Their length can vary from 8 in (20 cm) to over 3 ft (1 m) with weight of up to 100 pounds (50 kg).

Famous quotes containing the word evolution:
“As a natural process, of the same character as the development of a tree from its seed, or of a fowl from its egg, evolution excludes creation and all other kinds of supernatural intervention.”
—Thomas Henry Huxley (1825–95)
“By contrast with history, evolution is an unconscious process. Another, and perhaps a better way of putting it would be to say that evolution is a natural process, history a human one.... Insofar as we treat man as a part of nature—for instance in a biological survey of evolution—we are precisely not treating him as a historical being. As a historically developing being, he is set over against nature, both as a knower and as a doer.”
—Owen Barfield (b. 1898)
“Analyze theory-building how we will, we all must start in the middle. Our conceptual firsts are middle-sized, middle-distanced objects, and our introduction to them and to everything comes midway in the cultural evolution of the race.”
—Willard Van Orman Quine (b. 1908)
