After closely studying the structurally similar enzymes,CKα-2, APH(3′)-IIIa, and PKA,researchers observed that PKA had less insertions to its structural core compared to the other enzymes. Against this background,it is believed that CKα-2 have evolved from PKA to have more structural elements attached to it.

Famous quotes containing the word evolution:
“The evolution of a highly destined society must be moral; it must run in the grooves of the celestial wheels.”
—Ralph Waldo Emerson (1803–1882)
“The evolution of sense is, in a sense, the evolution of nonsense.”
—Vladimir Nabokov (1899–1977)
“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)
