Reproductive variation is central to evolution. All else in evolutionary theory follows directly or indirectly from the fact that organisms reproduce with variation.
...The driving force of weather is the sun.
No. It is merely one of many parameters that influence the direction of evolution, and can actually be a driving force in evolution. For example, the rise of warm-blooded mammals as a result of colder climate (a clear period of limited food resources) caused by climatic or astronomical phenomena, like the impact of a meteor.
Thomas Hunt Morgan? Probably because working with his flies he saw large mutational events that lead him to a saltationist position. That the greatest driving force in evolution is mutation. He was a geneticist before the new synthesis showed the true power of natural selection.
To understand the universe.
To Darwin, the central concept of organic evolution was natural selection. He proposed that individuals with advantageous traits are more likely to survive and reproduce, passing those traits on to their offspring, leading to changes in the characteristics of a population over time.
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"
Charles Darwin's theory on the driving force of evolution is called natural selection. This theory proposes that individuals with advantageous traits are more likely to survive and reproduce, passing those traits on to future generations. Over time, this leads to the accumulation of beneficial traits in a population.
Charles Darwin found that finches on the Galapagos Islands had variations in their beak shapes that were well-suited to the different types of food available on each island. This observation led him to develop his theory of natural selection as a driving force of evolution.
Darwin's theory of evolution by natural selection provided a mechanism for how species change over time. Specifically, it emphasized the role of adaptation to the environment as the driving force behind evolution, while earlier theories lacked a specific mechanism to explain how evolution occurred.
Social Darwinists believed that society should operate based on natural selection principles, with the fittest individuals or groups rising to the top. They argued that competition and inequality were necessary for progress and that government intervention in social and economic affairs was detrimental to the natural order.
Natural selection is the mechanism proposed by Charles Darwin to explain how species evolve over time. It is the process by which individuals with advantageous traits are more likely to survive and reproduce, leading to the gradual accumulation of beneficial traits in a population. Essentially, natural selection is the driving force behind the process of evolution as outlined by Darwin.
Charles Darwin suggested that organisms slowly acquired physical characteristics through a process called natural selection, where individuals with favorable traits are more likely to survive and reproduce, passing those traits on to future generations.
adaptation and natural selection
The advent of the T-1 carrier as the preferred transmission medium was the principle force driving the evolution of the PBX
The Nazi's believed that "the driving force in history was race."
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.
