"WebLife history patterns evolve by natural selection, and they represent an "optimization" of tradeoffs between growth, survival, and reproduction. One tradeoff is between number of offspring produced and the amount of energy (both physical resources and parental care) put into each offspring. Timing of first reproduction is another tradeoff.
