Those behaviours that are influenced by heritable factors are subject to natural selection. For most animals, all behaviour is, to some degree, the result of or at least affected by heritable factors.
These plants and animals were subjected to artificial selection so that the traits humans wanted in the organisms were selected for and the organisms not having these traits were culled. This, with some modification, is a good analogue for natural selection and artificial selection shows how organisms can be shaped over time with the proper selective pressures. The selective pressure of humans in artificial selection and the selective pressure of the environment in natural selection.
An organism is born with inherited traits, such as physical characteristics and behavior, that help it to survive and reproduce in its environment. These traits are shaped by evolution and natural selection, allowing the organism to adapt to its surroundings over generations.
Yes, adaptations can manifest as physical characteristics that enhance an organism's survival and reproduction in a particular environment. These physical traits are typically the result of genetic changes that confer a survival advantage. Complex behaviors can also be adaptations, as they help organisms interact with their environment and increase their fitness. Both physical characteristics and behaviors can be shaped by natural selection.
Behaviorism theory suggests that people's behavior is influenced by external stimuli in the environment. This theory emphasizes the importance of observable behavior and how it can be shaped through reinforcement and punishment.
The Theory of Modern Synthesis, also known as the Neo-Darwinian synthesis, is a comprehensive framework that integrates Charles Darwin's theory of evolution by natural selection with Mendelian genetics. It emphasizes the role of genetic variation and mutation in evolution, explaining how these genetic changes can lead to adaptations and speciation over time. This synthesis unites various biological disciplines, including genetics, paleontology, and ecology, to provide a more complete understanding of evolutionary processes. It highlights that evolution occurs through the gradual accumulation of small genetic changes shaped by natural selection, rather than through large, abrupt transformations.

Survival characteristics that have evolved through natural selection in plants includes things such as broad leaves, cone shaped trees, and waxy leaves.
A simplified example of mating behavior. If young men wanted old women as mates their genes would be selected out, as they would have few children to pass those genes to, until negative frequency selection reduced these allele in the gene pool. Men who desire young, fertile women as mates leave many descendents that carry the genes for this trait. So, over generations the mating behavior of men is shaped. and stabilizing selection keeps this mating trait/allele at high frequency in the populations gene pool.
Evolutionary psychology focuses on how human behavior and mental processes have been shaped by natural selection over time. It seeks to understand how evolutionary processes have influenced traits such as perception, cognition, emotion, and social behavior.
Evolutionary psychology is the perspective that describes behavior in terms of what best suits an organism for successful reproduction and survival. It focuses on how natural selection has shaped human behavior in order to enhance evolutionary fitness.
This aligns with the perspective of evolutionary psychology, which emphasizes how human behaviors have evolved and persisted over time due to their adaptive function in helping individuals survive and reproduce. By studying how these behaviors have been shaped by natural selection, psychologists can gain insights into understanding human psychology and behavior in a modern context.

An organism is born with inherited traits, such as physical characteristics and behavior, that help it to survive and reproduce in its environment. These traits are shaped by evolution and natural selection, allowing the organism to adapt to its surroundings over generations.
Evolutionary psychology would be most concerned with behavior changes that promote survival in the face of environmental pressures. This approach focuses on how psychological traits and behaviors have evolved to enhance survival and reproductive success. It examines how natural selection has shaped human cognition and behavior to adapt to the demands of the environment.
Psychologists study the evolution of behavior by examining how certain behaviors may have evolved over time to help individuals survive and reproduce. They use evolutionary principles to understand how certain traits and behaviors have been shaped by natural selection in response to environmental pressures. This approach helps researchers understand the adaptive functions of behaviors and their impact on human behavior today.
Yes, natural selection acts on preexisting genetic variation within a population. Individuals with traits that give them a survival or reproductive advantage are more likely to pass on their genes to the next generation, leading to an increase in the frequency of those advantageous genes in the population over time.
