The debate between "blank-slate" denial of the influence of heritability, and the view admitting both environmental and heritable traits, has often been cast in terms of nature versus nurture. These two conflicting approaches to human development were at the core of an ideological dispute over research agendas throughout the second half of the ...
In the context of the nature-nurture debate, interactionism is the view that all human behavioral traits develop from the interaction of both "nature" and "nurture", that is, from both genetic and environmental factors.
All evolutionarily-influenced characteristics in the phenotype of adults develop, and this requires examining not only the functioning of these characteristics in adults but also their ontogeny. All evolved characteristics develop via continuous and bidirectional gene-environment interactions that emerge dynamically over time.
Given that sexual reproduction is the means by which genes are propagated into future generations, sexual selection plays a large role in human evolution. Human mating, then, is of interest to evolutionary psychologists who aim to investigate evolved mechanisms to attract and secure mates. [93]
Hereditarianism is the research program according to which heredity plays a central role in determining human nature and character traits, such as intelligence and personality. Hereditarians believe in the power of genetic influences to explain human behavior and solve human social-political problems.
Evolutionary psychologists consider Charles Darwin's theory of natural selection to be important to an understanding of psychology. [1] Natural selection occurs because individual organisms who are genetically better suited to the current environment leave more descendants, and their genes spread through the population, thus explaining why organisms fit their environments so closely.

Human behavioral ecology (HBE) or human evolutionary ecology applies the principles of evolutionary theory and optimization to the study of human behavioral and cultural diversity. HBE examines the adaptive design of traits , behaviors , and life histories of humans in an ecological context.
The increase in algal biomass feedback to influence the evolution of other guppy traits. So evolutionary changes in the life-history traits of Trinidadian guppies caused by predation resulted in ecological effects at the community and ecosystem level, which feedback to influence the evolution of other traits in the guppies.
