Document Summary
Animal may be mature at birth and reproduce immediately. Produce high quality offsprings throughout entire life, and large numbers of them. There is something limiting the population size in a particular environment. It is hard to do all of these at the same time, as it may be incompatible with each other. Lineages have to make decisions over evolutionary time. Constraints and trade offs exist which prevents this from existing. Thrip = lays an egg, egg mite that parasitizes the egg of this species. One male and several females female mates with brother, and then devour the mother from the inside. Females then emerge, and mature, where they have already been inseminated. The amount of energy you get is limited due to biological processes take time. Different lineages of animals make different decisions and take different pathways. Every animal on earth today has been making these decisions since forever.
