Evolutionary tradeoffs can be present in a form called life history tradeoffs, which can be defined as the decrease in fitness (essentially, lifetime reproductive success) caused by one life history trait as a result of the increase in fitness caused by a different life history trait. [5] Life history traits are traits closely linked to fitness ...
Life history theory (LHT) is an analytical framework [1] designed to study the diversity of life history strategies used by different organisms throughout the world, as well as the causes and results of the variation in their life cycles. [2]
In economics a trade-off is expressed in terms of the opportunity cost of a particular choice, which is the loss of the most preferred alternative given up. [2] A tradeoff, then, involves a sacrifice that must be made to obtain a certain product, service, or experience, rather than others that could be made or obtained using the same required resources.
In health economics, time trade-off (TTO) is a technique used to measure the quality of life that a person or group is experiencing. An individual will be presented with a set of directions such as: An individual will be presented with a set of directions such as:
Life history may refer to: Life history theory, a theory of biological evolution that seeks to explain aspects of organisms' anatomy and behavior by reference to the way that their life histories have been shaped by natural selection; Life history (sociology), the overall picture of an informant's or interviewee's life
In life history theory, the cost of reproduction hypothesis is the idea that reproduction is costly in terms of future survival and reproduction. This is mediated by various mechanisms, with the two most prominent being hormonal regulation and differential allocation of internal resources.
Grafen's key equations show the necessity of marginal cost and differential marginal cost, nowhere in his paper was Grafen able to show the necessity of wasteful equilibrium cost (a.k.a. handicap). Grafen's model is a model of condition dependent signalling that builds on a traditional life-history trade-off between reproduction and survival.
Secondly, the recent evolution of chimpanzees and humans has been in completely different environments, with different survival needs. Therefore, the difference in working memory capabilities and other cognitive functions discussed by Matsuzawa might be adaptive rather than "tradeoffs".
