I was asked if the fitness of a fitness landscape is absolute or relative. Fitness landscapes are usually graphed with a fitness function that uses either phenotypes or genotypes in relation to ...

The wikipedia definition of Absolute fitness is "the ratio between the number of individuals with that genotype after selection to those before selection. It is calculated for a single generation and ...

I know that this is a contentious topic and I found conflicting explanations online which is what prompted me to put his question up. In some papers, Kin selection is mentioned based off the concept ...

I created a model where I calculate the survival probabilities from a Mark-recapture design. I'm wondering if I can call the survival probabilities as "relative fitness". Phenotype or genotype: $...

Looking at a picture of a seriously fat cat, apparently directly nurtured by humans, popping up in a language learning app, I started wondering: do animals "in the wild" (this might be ambiguous, but ...

How does natural selection process escape from local optima towards global optimum in a fitness landscape during evolution?

I would like to calculate selection gradients in order to gain insight into the strength and type of selection influencing my study population. (see here for review. http://jgking.web.unc.edu/files/...

I've read a couple of paper on Fisher's Fundamental Theory of Natural selection that states: $W(t+1) = W(t) + Var_{W}(t)$ Given a population with some degree of genetic variability, and assuming that ...

Animals like gorillas seem to have a physical fitness and muscle mass that don't depend as strongly on how much exercise they get, compared to humans. E.g. gorillas living in the wild sleep and rest a ...

What's the difference biological fitness and reproductive success in the biological terminology?

I am planning a fitness assay of Drosophila melanogaster. I'd like to get a good measure of lifetime reproductive success (lrs) but I don't want to count all the offspring produced over a lifetime by ...

In Grant 1986, it says: For this analysis the absolute fitness of an individual id scored as 0 if it disappeared and 1 if it survived, and these scores are then ...

I'm looking for bird studies that have found either a negative correlation or no correlation between habitat quality and reproductive success. Or in other words, bird studies that have found that ...

Apologies if this question it too open-ended; evolutionary biology is not my primary field. I have been reading a lot about the use of statistical mechanics in analyzing evolutionary dynamics. As an ...

I remember coming across a popular science article years ago about a monkey species which featured two male genotypes: the first were good looking males who acquired social status (as alphas or betas) ...

Say someone eats 100 calories of chocolate vs. 100 calories of carrots. Something tells me that eating the chocolate will lead to you generating more fat. Will it? Is it harder to burn the calories ...
