A genetic strategy an organism uses to survive, grow, and reproduce. Iow, a body grows the way it does for a reason. Reproduction is analogous to passing on the baton in a never-ending relay race. Evolution sculpts genomes to thrive in given environments. Genomes also have wiggle room to deal with unpredictable conditions.
