Those seeds will grow into more dandelions that will compete with each other as well. Humans often fancy themselves as being dandelions, when in fact they are much more like ants. Infants must receive constant care, nourishment, attention, and stimulation, or they will fail to mature. Children spend years and years learning from adults about how the world works, where they fit into it, and what society expects of them. People never stop learning these things.
Humans depend on each other for friendship, understanding, love, and well-being at every age.
People must all connect with other people to be healthy and to feel alive. People also specialize in society, just as ants do, so that they may provide more advanced goods and services to the society. When people in a society specialize, the farmers may produce more food, the builders can construct more houses, the manufacturers can produce more goods. This has proven more efficient than having each person grow his or her own food, build his or her own house, and create his or her own clothing and furniture. While ants have neurotransmitters and instinct to communicate to each member of the colony what strategy will be beneficial to the colony, humans have the body of knowledge that all children should be taught.
