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.

The phylum as a whole has adult bilateral symmetry and cephalization (the development of a head with sensory organs, in most members). Flatworms have three tissue layers: ectoderm, mesoderm and endoderm and a body plan that is acoelomate and sac-like with a single opening.seudocoelomate animals (such as roundworms) have a body cavity but it does not develop from splitting of the mesoderm embryonic tissue layer.Coelomate animals (humans, fish, shrimp, such as shown in Figure 4) have a body cavity lined with mesoderm cells.
