As a naturalist‚ Darwin constantly gathered facts‚ and observations of the natural world. He allegedly used an inductive system of inquirer that reviled generalization or universal truths. Howbeit‚ Darwin retained within his science a hypothetico-deductive method that formulated a hypothesis which created testable experiments on an empirical scale. As well as‚ Darwin understood that hypotheses allowed for the interaction between the development of creative predictions and viability of these ideas

Fuentes book. These four major approaches focus on natural selection. These approaches are‚ Human Behavioral Ecology‚ Evolutionary Psychology‚ Dual Inheritance Theory‚ and Memetics. Human Behavioral Ecology is the study of behavior from ecological and evolutionary perspectives with the goal of linking ecological factors and adaptive behavior. (Krebs and Davies 1997). Evolutionary Psychology is understanding the evolution of psychological mechanisms resulting in human behavior. Dual Inheritance Theory

from evolution and attempts to explain and examine social behavior within that context. Often considered a branch of biology and sociology‚ it also draws from ethology‚ anthropology‚ evolution‚ zoology‚ archeology‚ population genetics‚ and other disciplines. Within the study of human societies‚ sociobiology is very closely allied to the fields of human behavioral ecology and evolutionary psychology. Sociobiology investigates social behaviors‚ such as mating patterns‚ territorial fights‚ pack hunting

Although he did not consider the idea that different organisms were related by descent‚ he devised a system that placed these organisms in a hierarchy.

Rice‚ Urban Friberg‚ and Sergey Gavrilets. The common occurrence of homosexuality is perplexing from an evolutionary perspective. From an evolutionary standpoint‚ homosexuality is a trait that would not be expected to develop and persist in the face

agendas today are inspired by social-Darwinism‚ which is the idea that the strong will out compete the weak and eventually make for an improvement in population (de Waal‚ 1999). This is a main reason why categories of suppressed people fail to see biology in good light. These things are continuing to fade away though because a connection between genes and behavior is getting larger and larger. Studies now prove that you can like

homologies because the splitting events and common ancestors existed in the past and cannot be directly observed. There are two methods of phylogenetic inference: 1. Parsimony. Species are arranged in a phylogeny such that the smallest number of evolutionary changes is required. 2. Distance (or similarity.)
