Dr. Alveda King remarked the error of Planned Parenthoodâs abortion-on-demand corporate ideology: The most obvious practitioner of racism in the United States today is Planned Parenthood, an organization founded by the eugenicist Margaret Sanger and recently documented as ready to accept money to eliminate black babies.
Cephalization is considered an evolutionary trend, whereby nervous tissue, over many generations, becomes concentrated toward one end of an organism. This process eventually produces a head region with sensory organs.Cephalization is intrinsically connected with a change in symmetry.It accompanied the move to bilateral symmetry made in flatworms, with ocelli and pinnae placed in the head region.his process eventually produces a head region with sensory organs.

Flatworms are unsegmented, bilaterally symmetrical worms that lack a coelom (acoelomate) but that do have three germ layers. Some forms are free living but many are parasitic.Flatworms have a cephalized nervous system that consists of head ganglion, usually attached to longitudinal nerve cords that are interconnected across the body by transverse branches.onparasitic forms have a simple, incomplete gut; even this is lacking in many parasitic species. Movement in some flatworms is controlled by longitudinal, circular, and oblique layers of muscle. Others move along slime trails by the beating of epidermal cilia.
