When studying and proving the theory of evolution, Darwin notice that variations existed within species. Species includes organisms that are closely related and can mate to produce fertile offspring. Variation is a difference. Darwin noticed that there were more than one organism inside a species.
What else can I help you with?
What did Charles Darwin say about variation within species?
Because there is variation within a species, it is therefore possible for the law of natural selection to operate, by selecting those variations which best enhance survival and reproduction.
What are specific examples of variation within a species?
Human species, as in the variation in height.
Charles Darwin came to realize that organisms of the same species are identical?
The statement that Charles Darwin came to realize that organisms of the same species are identical is false. Charles Darwin observing the finch population in the Galapagos discovery quite the opposite was true. The finch has branch off with many adaptation to suit the changes in the different environments.
Which major ideas did Charles Darwin introduce in his writings?
Charles Darwin introduced the theory of evolution through natural selection, which posits that species evolve over time due to the survival and reproduction of individuals with advantageous traits. He emphasized the importance of variation within species and the role of environmental pressures in shaping these traits. Additionally, Darwin's work highlighted the interconnectedness of life forms, suggesting that all species share a common ancestor. His seminal work, "On the Origin of Species," laid the foundation for modern evolutionary biology.
Explain why there is more variation between a species than within a species?
Within a species, the animals breed together so that the similar characteristics are passed from parents to their offspring. This is why there is less variation within a species than between a species.
Variation exists within the genes of every population or species as the result of what?
Variation exists within the genes of every population or species as the result of natural selection. The other reason is due to neutrality of mutations.
What did Charles Darwin say about variation within species?
Because there is variation within a species, it is therefore possible for the law of natural selection to operate, by selecting those variations which best enhance survival and reproduction.
Does variation within the same species exist?
Of course, variation exists within individuals of the same species. This is because there are a small minority of genes which have multiple alleles in most species. In cases where a subset of the population is isolated from the rest of the population, a subspecies may develop which has particular unique characteristics but can still interbreed with the rest of the species.
What are specific examples of variation within a species?
Human species, as in the variation in height.
Why was variation the weakest concept in Darwin's theory?
Variation?!?! That was an obvious observation of naturalists that opposed Darwin's concepts totally. Unless you mean the heritability that leads to variation? Explaining that variation was the problem. Creationists of the time explained this by positing god's whimsy in designing his species, but this was shown to be nonsense as natural processes are at work in variation and this can be shown experimentally. The concept of natural selection explained how that natural variation was selected on beneficial traits. What Darwin did not understand is how that variation was passed on to progeny. His explanation was wrong.
What are the four major points of Darwin?
Species evolve over time through a process of natural selection. All species share a common ancestor. Variation exists within populations, leading to differential survival and reproduction. Evolution is driven by the accumulation of small, gradual changes over long periods of time.
Which process produces the most variation within a species?
Variations occurs in species due to the process of "Crossing over"
Is mango leaf a parallel variation?
No, mango leaf is not considered a parallel variation. Parallel variation refers to easy and reversible changes within a species or population, while mango leaf characteristics are part of the natural variation within the species.
What is a major cause of variation within species?
Genetic variation, caused by mutations in DNA, is a major source of variation within species. Mutations can lead to differences in traits such as color, size, and behavior, allowing for natural selection to act upon these variations.
Charles Darwin came to realize that organisms of the same species are identical?
The statement that Charles Darwin came to realize that organisms of the same species are identical is false. Charles Darwin observing the finch population in the Galapagos discovery quite the opposite was true. The finch has branch off with many adaptation to suit the changes in the different environments.
Main points of darwin's theory of evolution?
Darwin's theory of evolution is based on the concept of natural selection, where individuals that are better adapted to their environment are more likely to survive and reproduce. Over time, this process leads to the accumulation of beneficial traits within a population, resulting in the gradual change of species. Additionally, Darwin's theory highlights the importance of variation within a population, genetic inheritance, and the gradual divergence of species over long periods of time.
What two key insights allowed Darwin to come up with the theory of natural selection?
Darwin's key insights in developing the theory of natural selection were the concept of variation within a population and the idea of differential survival and reproduction. He realized that individuals within a species exhibit variation, and those with traits better suited to their environment are more likely to survive and pass on their traits to the next generation.
