∙ 11y agoIn evolutionary Biology, fitness is defined as the reproductive capacity of a particular genotype, relative to another.
For example, consider a hypothetical genotypic variant in birds that enables birds which possess it to fledge, on average, 20% more offspring than birds possessing a different variant. The first variant is said to be the fitter of the two, and over time, will become more common in the population, all other things remaining equal.
Darwin talks about survival of the fittest. Every organism has a variety of different attributes; the shape of their teeth, the length of their fur, the type of digestive enzymes they secrete, and so forth. Every organism, to be successful, must have some ecological niche that it fills. It does not need to be good at everything (for example, some species swim very well, some don't; some can fly, some can't, and so forth) but it does need to be good at something. The degree to which a given organism is good at what it does, would define the fitness of that organism.

In evolutionary terms an organisms fitness is measured by its?
contribution to the gene pool of the next generation
From an evolutionary stand point fitness is measured in?
Reproductive success is the coin evolution pays in.
What is weak altruism?
Weak altruism suggests that individuals have a predisposition to help others, even if it comes with some costs to themselves. It is characterized by selfless actions that benefit others, although the individual may also experience personal gains in the process. This concept acknowledges the complex nature of altruistic behavior and the potential mix of motives involved.
How do you measure your strengths and weaknesses in terms of your fitness level how is your fitness test How do you self assess your fitness level?
You can measure your strengths and weaknesses in terms of your fitness level using measurable performance parameters such as the number of games you have won.
What is meant by fitness in Darwinian evoultion?
Darwinian fitness measures the reproductive success of a species. This measures how much of a contribution a specific individual contributes to their species' gene pool, and whether certain gene mutations within an individual will or will not have an overall effect on the gene pool of a species as a whole.
In an evolutionary sense an individual organism has high fitness if it?
reproduces more successfully than other individuals.
What are the evolutionary advantages achieved by the myelinatio of neurons?
Myelin allows for much faster conduction speeds. Faster is better in evolutionary terms.
What involves the application of evolutionary principles to the behavior of animals and humans?
The behavior of animals and humans can be studied with an evolutionary lens. This allows scientists to determine why certain behaviors were beneficial in evolutionary terms.
The success of a organism in surviving and reproducing is a measure or its?
Fitness (in Darwinian terms).
What are the criteria of success in terms of evolution by natural selection?
The fitness of a variant is expressed in terms of the average number of offspring.
Why does the phrase survival of the fittest does not accurately reflect Darwins concept of evolutionary fitness?
Darwin's concept of evolutionary fitness refers to how the genes reproduced through generations are those that are necessary to survival. So, if an organism has a genetic trait that makes it susceptible to prey, then it gets killed and cannot pass its genetic information to offspring. So, its trait is lost over time. This is Darwin's concept. The phrase "survival of the fittest" is not accurate in terms of Darwin because it refers to strong organism, which is not necessarily the case in terms of survival through genetic traits. These traits may be present in a small, weak organism, which may not seem strong and physically fit, but its genes are still passed on since it survives
