style="font-size:15px;"> As we tell the evolutionary story, we are reminded that there is more to the universe than the human mind can grasp, and that we seek models to try to understand our existence – scientific, religious, and artistic models among others. We can relate what we know from a scientific perspective (primarily from fossil record) about the origin of life and the development of the species, but fact goes hand in hand with mystery. When a new discovery is made, the whole picture shifts. Thus, our information is constantly changing, and the insights we have as individuals are part of the discovery. ❖

Body symmetries
20 minutes
Lying on the floor on your belly, arms and legs spread in an X: Slowly lift one arm about an inch off the floor, feel its weight, and let it return to the floor. Repeat with a leg, your head, then the pelvis. Let all of your weight rest into the floor.
❍ Asymmetry: Imagine that you are suspended in water. Begin moving slowly, brushing all surfaces of your body against the floor or another body part as though stimulated by the water. You are free from gravity. Continue moving nondirectionally, following impulses for movement and responding to sensations. This form of body symmetry is called asymmetry. An example would be a single-celled amoeba suspended in the water today. In this symmetry, no one part of the body surface has priority over another part.
