| Life is a major source of complexity, and evolution is the major process behind the varying forms of life. In this view, evolution is the process describing the growth of complexity in the natural world and in speaking of the emergence of complex living beings and life-forms, this view refers therefore to processes of sudden changes in evolution. | | Life is a major source of complexity, and evolution is the major process behind the varying forms of life.

| Life is thought to have emerged in the early RNA world when RNA chains began to express the basic conditions necessary for natural selection to operate as conceived by Darwin: heritability, variation of type, and competition for limited resources. Fitness of an RNA replicator (its per capita rate of increase) would likely be a function of adaptive capacities that were intrinsic (in the sense that they were determined by the nucleotide sequence) and the availability of resources. The three primary adaptive capacities may have been (1) the capacity to replicate with moderate fidelity (giving rise to both heritability and variation of type); (2) the capacity to avoid decay; and (3) the capacity to acquire and process resources. These capacities would have been determined initially by the folded configurations of the RNA replicators (see “Ribozyme”) that, in turn, would be encoded in their individual nucleotide sequences. Competitive success among different replicators would have depended on the relative values of these adaptive capacities. | | Life is thought to have emerged in the early RNA world when RNA chains began to express the basic conditions necessary for natural selection to operate as conceived by Darwin: heritability, variation of type, and competition for limited resources.

| An example to consider in detail is an ant colony. The queen does not give direct orders and does not tell the ants what to do. Instead, each ant reacts to stimuli in the form of chemical scent from larvae, other ants, intruders, food and buildup of waste, and leaves behind a chemical trail, which, in turn, provides a stimulus to other ants. Here each ant is an autonomous unit that reacts depending only on its local environment and the genetically encoded rules for its variety of ant. Despite the lack of centralized decision making, ant colonies exhibit complex behavior and have even demonstrated the ability to solve geometric problems. For example, colonies routinely find the maximum distance from all colony entrances to dispose of dead bodies. | | An example to consider in detail is an ant colony.

− | 需要详细考虑的一个例子是蚁群。蚁后不会直接下达命令,也不会告诉蚂蚁该做什么。相反,每只蚂蚁对来自幼虫、其他蚂蚁、入侵者、食物和排泄物的化学气味的刺激作出反应,并留下化学痕迹,这反过来刺激其他蚂蚁。在这里,每只蚂蚁都是一个自主的单元,它们的反应仅仅取决于它们所处的局部环境和它们的蚂蚁种类的遗传编码规则。尽管缺乏集中化的决策,蚁群仍能表现出复杂的行为,甚至被证明具有解决几何问题的能力。例如,蚁群会按照一定的例行规则找到距离所有蚁群入口的最大距离来处理尸体。
