adaptation and natural selection
Natural selection is the process of certain animals being more successful than others and thus reproducing more. It is the driving force behind evolution as we currently understand it.
Natural Selection
The advent of the T-1 carrier as the preferred transmission medium was the principle force driving the evolution of the PBX
Natural selection, where organisms with beneficial traits are more likely to survive and reproduce, is the biggest force driving evolution. This process leads to the accumulation of adaptations over time that increase the fitness of species within their environments.
Natural selection--evolution is survival of the fittest. Weaker animals die, and stronger animals survive. Genetic variation--this allows for animals of the same species to have different traits (some of which may be more favorable and through evolution will become the norm for the species) - Genetic drift also plays a role; It's when the gene pool of a population is changed because of an accident, etc. - Gene flow is when individuals from different populations migrate and introduce their genes into another population's gene pool Mutation--sometimes genetic mutation allows for new, favorable traits to appear.
Reproductive variation is central to evolution. All else in evolutionary theory follows directly or indirectly from the fact that organisms reproduce with variation.
Natural selection is a key driving force of evolution, whereby traits that provide a survival or reproductive advantage are favored and passed on to future generations. Other factors such as genetic drift, mutation, and gene flow also play a role in shaping the diversity of species over time.
The driving force behind behavior that arises from within a person is often their internal motivations, desires, beliefs, emotions, and values. These internal factors can influence a person's decisions and actions, shaping their behavior and responses to various situations and stimuli.
The driving force behind the principles of physics is the pursuit of understanding and explaining the fundamental laws that govern the behavior of the universe. Physics seeks to uncover the underlying principles that govern the interactions of matter and energy, and to use this knowledge to predict and explain the behavior of physical systems.
The word for the cause of a behavior is "motivation." It refers to the reason or driving force behind an individual's actions, desires, or needs that lead them to behave in a certain way.
Charles Darwin Published "On the origin of species by means of natural selection" in 1859. He was not the first to postulate evolution. His grandfather Erasmus Darwin advanced the theory of evolution 75 years earlier. Charles Darwin gave us the driving force "natural selection"
