"This is an evolutionary process in which they have moved in the right direction," Mr. Harrington, the American envoy, said.
We present results for a sequential evolutionary process in which L successive transitions propel a population from a "wild-type" state to a given "terminally differentiated," "resistant," or "cancerous" state.
This has its roots in emotion, in which what is pleasant or unpleasant, a reward or punisher, is the result of an evolutionary process in which genes define the (pleasant or unpleasant) goals for action.
The transition of cells through the different stages from normal to cancerous can be thought of as an evolutionary process, in which there occurs a succession of genetic changes that undergo selection and determine the ultimate genotype (genetic constitution) of a tumour and its metastases.
However, besides the delay effect, an impulsive effect likewise exists in a wide variety of evolutionary process, in which states are changed abruptly at certain moments of time.
One symptom of a teleological conception of evolutionary relationships is a ladderized interpretation of the evolutionary process in which "primitive" species give rise to "advanced" species.
However, impulsive differential equations [3, 4] are also suitable for the mathematical simulation of evolutionary processes in which the parameters state variables undergo relatively long periods of smooth variation followed by a short-term rapid change in their values.
However, besides delay effect, impulsive effect likewise exists in a wide variety of evolutionary processes in which states are changed abruptly at certain moments of time, involving fields such as medicine and biology, economics, mechanics, electronics, and telecommunications.
