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.
Millions of years of adaptive change to the immediate environment. Natural selection and sexual selection in humans have shaped our bodies to preform the survival and reproductively successful algorithms that " promote " genes into the next generation. Even our faces are products of selection, sexual selection, as women drive this evolution in men by being the sex that chooses to be with a partner.
Natural selection has shaped the evolution of modern elephants through adaptations that enhance their survival and reproductive success in diverse environments. Ancestors of modern elephants faced changing climates and habitats, leading to traits such as larger body size for thermoregulation, long trunks for foraging, and social behaviors for protection and resource sharing. Over time, those individuals with advantageous traits were more likely to survive and reproduce, gradually leading to the emergence of the modern elephant species we see today. These adaptations have allowed elephants to thrive in various ecosystems across Africa and Asia.
Yes, it is normal for hamsters to eat their own feces. This behavior, known as coprophagy, helps them digest their food better by giving them another opportunity to absorb nutrients from their food. It is a natural and necessary behavior for their digestive system.

Survival characteristics that have evolved through natural selection in plants includes things such as broad leaves, cone shaped trees, and waxy leaves.
Yes, behavior can be shaped through natural selection. Traits that increase an individual's chances of survival and reproduction are more likely to be passed on to future generations, including behaviors that contribute to these outcomes. Over time, this can result in the evolution of certain behavioral patterns that enhance an organism's fitness in its environment.

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.
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.
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.
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.
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.
