TL;DR: A genetical mathematical model is described which allows for interactions between relatives on one another's fitness and a quantity is found which incorporates the maximizing property of Darwinian fitness, named “inclusive fitness”.

TL;DR: It is suggested that characters which develop through mate preference confer handicaps on the selected individuals in their survival, which are of use to the selecting sex since they test the quality of the mate.

TL;DR: Information content may be used as a measure of the diversity of a many-species biological collection whereby the sample size is progressively increased by addition of new quadrats and the mean increment in total diversity that results from enlarging the sample still more provides an estimate of the Diversity per individual in the whole population.

TL;DR: The hypothesis that contemporary organisms are also randomly constructed molecular automata is examined by modeling the gene as a binary (on-off) device and studying the behavior of large, randomly constructed nets of these binary “genes”.

TL;DR: An antithesis to the view that gregarious behaviour is evolved through benefits to the population or species is presented, and simply defined models are used to show that even in non-gregarious species selection is likely to favour individuals who stay close to others.
