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:
“Historians will have to face the fact that natural selection determined the evolution of cultures in the same manner as it did that of species.”
—Konrad Lorenz (1903–1989)
“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)
“Family living can go on existing. Very many are
remembering this thing are remembering that family
living living can go on existing. Very many are quite
certain that family living can go on existing. Very
many are remembering that they are quite certain that
family living can go on existing.”
—Gertrude Stein (1874–1946)
“Man is more disposed to domination than freedom; and a structure of dominion not only gladdens the eye of the master who rears and protects it, but even its servants are uplifted by the thought that they are members of a whole, which rises high above the life and strength of single generations.”
—Karl Wilhelm Von Humboldt (1767–1835)
