As new species evolve they build up differences in the DNA from related species, as a result of mutation and selection.
The role of DNA is to encode the structure of proteins. The DNA code defines the sequence of amino acids in each protein.
So if the sequence of bases in the DNA changes, the sequence of amino acids in the proteins can also change as a result.
If we compare closely related species there should be fewer differences in their DNA and so fewer differences in their proteins than between distantly related species.
By comparing amino acid sequences we can therefore estimate how closely or distantly related two species are to each other.

What else can I help you with?
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 the gradual changes in species over time?
Gradual changes in species over time is known as evolution. This is a process where populations of organisms change over generations as a result of genetic variation, natural selection, and adaptations to their environment. Over time, these changes can lead to the formation of new species.
Which is part of the theory of evolution by natural selection A. Animals do not have variation within a species. B. Many small changes can eventually make a species very different. C. New generations?
B. Many small changes can eventually make a species very different.
What is meant by the term variation?
Variation refers to the differences or changes observed within a group of individuals, such as variations in traits, characteristics, or behaviors. It can be caused by genetic factors, environmental influences, or a combination of both. Variation is essential for evolution and the adaptation of species to changing environments.
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.
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.
How does variation in a species help the species survive?
As each new generation is produced, genetic variation may be introduced into a population. The more genetic variation in a population, the more likely it is that some individuals might have traits that will be advantageous if the environment changes.
What term describes changes that within species?
The term that describes changes within a species over time is "microevolution." This involves genetic variations that occur within a population, leading to changes in traits or characteristics in response to environmental factors.
What are specific examples of variation within a species?
Human species, as in the variation in height.
What are advantages of variation?
Advantage- On the species level, variation allows a population to maintain a healthy diversity, allowing it to cope with changing circumstances.Disadvantage- On the individual level, variation may lead to detrimental changes as well as neutral and beneficial changes.
What is the gradual changes in species over time?
Gradual changes in species over time is known as evolution. This is a process where populations of organisms change over generations as a result of genetic variation, natural selection, and adaptations to their environment. Over time, these changes can lead to the formation of new species.
What causes variation within species?
because the variation causes the variation becasue of the variation of the species. genetic mutation and adaption of some members to physical condition better than others (survival and reproduction of those best able to adapt to the environment. ) It can also be affected by the contact the species has doesn't have with other populations of the species.

Mutations are a source of what in a species?
Genetic variation, which can lead to evoloution, and then potentially a new 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.
What factors influence the evolution of a species?
The evolution of a species is influenced by factors such as natural selection, genetic variation, environmental changes, and reproductive success. These factors can lead to adaptations that help a species survive and thrive in its environment over time.
