Evolution of The Family Members
Phylogenetic analysis reveals that all Robo receptors have evolved from a common ancestral protein, with many subsequent diversification events occurring independently in different lineages. The Robo gene was initially identified in Drosophila and has since been cloned in various species including mice and humans. Drosophila have three Robo receptors: Robo1, Robo2, and Robo3. In vertebrates, four Robo receptors have been identified: Robo1, Robo2, Robo3/Rig-1, and Robo4/Magic Roundabout.

Famous quotes containing the words evolution of, evolution, family and/or members:
“Like Freud, Jung believes that the human mind contains archaic remnants, residues of the long history and evolution of mankind. In the unconscious, primordial “universally human images” lie dormant. Those primordial images are the most ancient, universal and “deep” thoughts of mankind. Since they embody feelings as much as thought, they are properly “thought feelings.” Where Freud postulates a mass psyche, Jung postulates a collective psyche.”
—Patrick Mullahy (b. 1912)

“O God, and the wedding! All her family and her friends
and only a handful of mine all scroungy and bearded
just wait to get at the drinks and food—”
—Gregory Corso (b. 1930)
“I rejoice that horses and steers have to be broken before they can be made the slaves of men, and that men themselves have some wild oats still left to sow before they become submissive members of society. Undoubtedly, all men are not equally fit subjects for civilization; and because the majority, like dogs and sheep, are tame by inherited disposition, this is no reason why the others should have their natures broken that they may be reduced to the same level.”
—Henry David Thoreau (1817–1862)
