What evidence do scientists use to prove that evolution has occurred?
Simple example. You know hair color is under genetic control. Two types, blond ( which is recessive ) and brown ( which is dominant ) exist in our population. These two alleles are in a 75% to a 25% frequency. ( dominant to recessive ) if that frequency changed to 60% to 40% you could say that evolution had taken place. Evolution is the change in allele frequency in a population of organisms over time. ( example very simplified ) PS Scientist do not prove things. They support their work with the evidence.
What is direct evidence of evolution?
direct evidence is the observation of evolution as it occurs. We have discovered novel genes conferring an advantage in an environment in which the ancestral population lacked those genes entirely. One example is flavobacterium that evolved nylonase enzymes. Antibiotic resistance is another example.
How can physiology be used as evidence of evolution?
Physiology can provide evidence of evolution by showing how certain traits or adaptations have evolved over time to enhance survival and reproduction. For example, studies on the physiological differences between closely related species can reveal how changes in gene expression or protein function have allowed for adaptation to different environments. By comparing physiological traits across different species, scientists can infer evolutionary relationships and the processes that have shaped them.
How are vegistigal structures an example of evolution?
Vestigial structures are remnants of organs or traits that were functional in ancestral species but are reduced or non-functional in present-day organisms. These structures provide evidence of evolution because they suggest that organisms have evolved from ancestors with different adaptations, and over time, structures that are no longer useful have become reduced or lost. This supports the idea that organisms have changed over time to adapt to their environment through the process of evolution.
Is it true similarities in early development are not evidence for evolution?
Similarities in early development can provide evidence for evolutionary relationships between species. For example, striking similarities in embryos of different vertebrate species support the idea of a common ancestor. These similarities suggest that evolutionary changes have occurred over time, leading to variations in adult forms while retaining aspects of shared developmental processes.
What is fossil evidence?
fossil evidence is when scientist study fossils to figure out how the animal died how it evoled
Can you provide an example of a theory that is falsifiable?
Yes, the theory of evolution by natural selection is an example of a falsifiable theory. This means that it can be tested and potentially proven wrong through empirical evidence.
Complete history of a theory of evolution?
There are many books that describe the theory of evolution. For example, there is a book called Evolution: The Remarkable History of a Scientific Theory.
Direct evidence about theory of evolution?
There are thousands of instances of direct evidence of evolution. The most well-known example is that of Darwin's Finches. These finches were observed through fossil records to have changed over time to adapt to their environment.
Describe an example of how natural selection influenced the evolution of a particular species?
a great example is the peppered moth. look up the full story in wikipedia
Which is an example of evidence of evolution based on comparative biochemistry?
An example of evidence of evolution based on comparative biochemistry is the presence of homologous proteins across different species that share similar sequences and structures, indicating a common evolutionary ancestor. By comparing the amino acid sequences of these proteins, scientists can trace the genetic relationships between different organisms and uncover their evolutionary history.
What an non-example of evidence?
An example of a non-example of evidence would be personal opinions or anecdotes that are not backed up by facts or data. This type of information does not provide objective support for an argument or claim.

Was Darwin's theory of evolution accurate to today's findings?
I suppose it is after all there are som many evidence about it for example the ancestor things to do with apes.
What is an example of evident?
Dinosaur bones, plant fossil, sealife fossil the evidence proves that there were animals long ago, and can support evolution
What is direct evidence of evolution?
direct evidence is the observation of evolution as it occurs. We have discovered novel genes conferring an advantage in an environment in which the ancestral population lacked those genes entirely. One example is flavobacterium that evolved nylonase enzymes. Antibiotic resistance is another example.
Can you provide an example of weak evidence in a criminal investigation?
Weak evidence in a criminal investigation could be a single unreliable witness testimony without any corroborating evidence, such as physical evidence or surveillance footage.
