 Strategy of Predator Satiation

An effective strategy of predator satiation involves two adaptations. First, the synchrony of emergence or reproductions must be very precise, thus assuring that hte market is truly flooded, and only for a short time. Secondly, this flooding cannot occur very often, lest predators simply adjust their own life cycle to predictable times of superfluity. If bamboos flowered every year, seed eaters would track the cycle and present their own abundant young with the annual bounty. But if the perio...

Cicadas have evolved the strategy of mass-producing in such numbers that the predators cannot eat them all.

 "Adaptation" is Not Teleological

In its essence, the theory of natural selection is primarily an attempt to give an account of the probable mechanism of the origin of the adaptations of the organisms to their environment, and only secondarily an attempt to explain evolution at large. Some modem biologists seem to believe that the word 'adaptation' has teleological connotations, and should therefore be expunged from the scientific lexicon. With this we must emphatically disagree. That adaptations exist is so evident as to be ...

It is not an end, neither is evolution, and this is not the best state of things there could be.

 The Evolutionary Arms Race

Before asserting that the deceptive appearance of a grasshopper or butterfly is unnecessarily detailed, we must first ascertain what are the powers of perception and discrimination of the insects' natural enemies. Not to do so is like asserting that the armour of a battle-cruiser is too heavy, or the range of her guns too great, without inquiring into the nature and effectiveness of the enemy's armament. The fact is that in the primeval struggle of the jungle, as in the refinements of civiliz...

 How the Analytical Engine Goes Beyond Mathematics

Again, it [the Analytical Engine] might act upon other things besides number, were objects found whose mutual fundamental relations could be expressed by those of the abstract science of operations, and which should be also susceptible of adaptations to the action of the operating notation and mechanism of the engine . . . Supposing, for instance, that the fundamental relations of pitched sounds in the science of harmony and of musical composition were susceptible of such expression and adapt...

Distinguished from the Difference Engine, Ada Lovelace describes how the Analytical Engine could produce logical outputs, not just the results of mathematical equations.
