The smallest unit that can evolve is the population, not the individual. In other words, you can't evolve, but over generations, the population can be subject to natural selection and different traits can be selected. In addition, the evolution of a population will take generations of fluctuating gene frequencies, something you can't just watch in action. Of course, the speed of evolution is entirely dependent on the environment; some populations will evolve quicker than others.

How did the ideas of Alfred Russell Wallace cpare to Darwin's ideas about natural selection and evolu tion?
Very closely in natural selection, but in some drivers of evolution, such as sexual selection, Wallace and Darwin disagreed on the fine points. Wallace could not accept female choice in sexual selection when Darwin posited this concept. Lively exchanges in letters were held over this disagreement.
Why were the Galápagos Islands so important to Darwin's formulation of natural selection?
The unique biodiversity and isolation of species on the Galápagos Islands allowed Darwin to observe variations and adaptations that influenced his understanding of natural selection. This diversity provided evidence supporting the idea that species could change over time to better suit their environment, leading to his formulation of the theory of evolution by natural selection.
Charles Darwin concluded that in similar environments around the world could produce similar structures in unrelated species?
Yes, Charles Darwin observed that in similar environments, unrelated species could independently evolve similar adaptations to survive and thrive. This phenomenon is known as convergent evolution, where organisms facing similar selective pressures develop similar traits or structures. Darwin's theory of evolution by natural selection explains how this process occurs over time.
How did Lamarck's theory of evolution vary from Darwin's?
Lamarck proposed that acquired traits could be inherited, while Darwin emphasized natural selection as the mechanism for evolutionary change. Lamarck's theory focused on an organism's individual efforts to adapt, whereas Darwin's theory highlighted the role of competition and environmental factors in shaping evolution. Despite both theories contributing to our understanding of evolution, Darwin's theory has gained more support due to its emphasis on genetic variation and natural selection.
When Darwin published his theory of evolution one strength of his work was?
The '' strength '' that really got it across to both scientists and lay people was the way he laid out his first chapter on artificial selection. People could progress from that fact of everyday life to natural selection much more easily than it could have been otherwise. Darwin deliberately wrote the book this way; '' one long argument. ''
Why did artificial selection interest Darwin?
Artificial selection interested Darwin because it demonstrated that traits could be modified over generations through selective breeding. This process allowed humans to intentionally choose which traits were passed on to offspring, leading Darwin to realize that a similar natural process could occur in nature, driving evolution through natural selection.
Who is the founder and co-founder of Darwin's theory natural selection?
The founder of the theory of natural selection is Charles Darwin. Alfred Russel Wallace independently developed a similar theory of natural selection around the same time as Darwin, leading to both scientists presenting their work together in a joint paper in 1858.
What did Darwin propose by saying that over a long natural selection could lead to?
Darwin proposed that over a long time, natural selection could lead to the gradual change and divergence of species from a common ancestor, resulting in the formation of new species through the process of adaptation to their environment.
How did the ideas of Alfred Russell Wallace cpare to Darwin's ideas about natural selection and evolu tion?
Very closely in natural selection, but in some drivers of evolution, such as sexual selection, Wallace and Darwin disagreed on the fine points. Wallace could not accept female choice in sexual selection when Darwin posited this concept. Lively exchanges in letters were held over this disagreement.
How the idea of artificial selection contributed to Darwin and idea on natural selection?
The concept of artificial selection, where humans selectively breed plants or animals for desired traits, helped Darwin understand the process of natural selection. He realized that if humans could influence changes in species through selective breeding, then nature could also act as a selective force, leading to the survival of organisms best suited to their environment. This insight informed Darwin's theory of evolution by natural selection, where the environment naturally selects for characteristics that provide a reproductive advantage.
What was the origin of species about?
It's about Charles Darwin's journey and discoveries on The Beagle. Also, Darwin believed all species had the same ancestor and evolved from them. There are 2 purposes: to 1. To explaining what natural selection is and how it could produce new species and2. Respond to objections that those who do not agree with natural selection might have
What well-known process was important in developing both Mendel's and Darwin's ideas?
Artificial Selection.
How did artificial selection influence Darwins theory of natural selection?
Artificial selection demonstrated that desirable traits could be purposefully selected and passed down in domesticated plants and animals. This helped Darwin understand that similar processes could occur in nature through natural selection, where organisms with advantageous traits are more likely to survive and reproduce. This supported his theory of evolution by natural selection.
How is natural selection used in artificial selection?
Natural variation in artificial selection is used because humans choose from among the naturally occurring variation s in species. Natural selection is related to species fitness because Darwin called natural selection survival of the fittest because those that could survive would carry their species on there for being the naturally selected.
British naturalist worked on the theory of evolution and natural selection?
This question could fit both Charles Robert Darwin and Alfred Russel Wallace in an answer as they both were British naturalists and both developed a theory of evolution by natural selection.
How is natural variations used in artificial selection?
Natural variation in artificial selection is used because humans choose from among the naturally occurring variation s in species. Natural selection is related to species fitness because Darwin called natural selection survival of the fittest because those that could survive would carry their species on there for being the naturally selected.
Why is Lamark not called the father of Evolution?
Because it was Darwin who made it a scientifically plausible explanation, by providing a mechanism by which evolution could occur....Natural Selection.
