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.
What are some of the criticisms of the theory of evolution?
The theory of evolution has many criticisms but none have proven evolution wrong. For example, some people argue that the bacterial flagellum is 'irreducibly complex' and therefore can not have evolved, even though the evidence shows that it not only could have, but has.
Is evolution a fact or theory?
Rather both. Evolution, the change in allele frequency over time in a population of organisms, is an observed and observable fact. The theory of evolution by natural selection explains this fact with overwhelming evidences from many different disciplines.
What is an example of micro evolution?
You are an example of human micro-evolution as the population of humans has changed allele frequency over time. Micro-evolution is just evolution; change over time.
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 fossil evidence?
fossil evidence is when scientist study fossils to figure out how the animal died how it evoled
Which is an example of evidence of evolution based on comparative biochemistry?
The fact that sheep insulin can be substituted for human insulin is an example of evidence of evolution based on comparative biochemistry. Insulin is a peptide hormone.
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.
Does a theory have to be supported by evidence?
NO. take Darwin's theory of evolution for example. there is no real evidence, but it is accepted as fact by most in America today.
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.
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
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 are some of the criticisms of the theory of evolution?
The theory of evolution has many criticisms but none have proven evolution wrong. For example, some people argue that the bacterial flagellum is 'irreducibly complex' and therefore can not have evolved, even though the evidence shows that it not only could have, but has.
What is an example of micro evolution in organisms?
example of an micro-evolution in an organism?
An example of a theory and an law?
A theory is an idea system with a lot of evidence to support it--for example, the theory of evolution. A law (in science) is an idea system with proof attached to it--no contradictions--example, the law of gravitation.
