Teleology in biology is the use of the language of goal-directedness in accounts of evolutionary adaptation, ... For example, the zoologist S. H. P. Madrell wrote ...
Telestrations is a party game in which players are prompted to sketch a word listed on a card, then guess what the other players have drawn. The game is produced by The Op (USAopoly). The game is produced by The Op (USAopoly).
Charles Darwin. The idea that the function of a trait might shift during its evolutionary history originated with Charles Darwin (Darwin 1859).For many years the phenomenon was labeled "preadaptation", but since this term suggests teleology in biology, appearing to conflict with natural selection, it has been replaced by the term "exaptation".
Example of how a telestrator might annotate a medical image shared during a telemedicine session. The telestrator was invented by physicist Leonard Reiffel , who used it to draw illustrations on a series of science shows he did for public television 's WTTW in Chicago in the late 1950s.
The exception to this is the flagellum, the only known example of a freely rotating propulsive system in biology; in the evolution of flagella, individual components were recruited from older structures, where they performed tasks unrelated to propulsion. The basal body that is now the rotary motor, for instance, might have evolved from a ...
For example, in the Chauvet-Pont-d'Arc Cave (circa 30,000 BC), at least 13 different species have been identified. [2] In one prehistoric cave (circa 15,000 BC), there is a drawing of a mammoth with a darkened area where the heart should be. If this is indeed the intention of the illustration, it would be the world's first anatomical ...

The concept of teleonomy was largely developed by Mayr and Pittendrigh to separate biological evolution from teleology. Pittendrigh's purpose was to enable biologists who had become overly cautious about goal-oriented language to have a way of discussing the goals and orientations of an organism's behaviors without inadvertently invoking teleology.
