How would you explain about the contribution of mutation in the evolution as it is deleterious for living cells?
Most mutation is neutral. For instance, if a gene codes for two different proteins as a result of mutation and both those proteins contain amino acids doing the same thing ( amino acids are grouped, hydrophobics, hydrophillics, acidic, etc. ) then protein function is not changed. Most mutations, of any kind, happen in encoding regions of the DNA. Some mutations, especially those leading to replicated proteins, are beneficial to an organism. Check on hemoglobin and immune system. Then there are some deleterious mutations, but do to difference in penetrance and expressivity in genes, some of these are not fatal, some have onset in older ages, and some can be ameliorated by treatement.
So, as you can see, this is very complex, but evolution has a long time to work in, so even very rare beneficial mutations can come to fruition, while the worst of the deleterious mutations are spread out over evolutionary time also.
What else can I help you with?
Can evolution explained by science?
Evolution, the change in allele frequency over time in a population of organisms, is explained by science. Natural selection, mutation, genetic drift and gene flow explain just about all of the basics of evolution.
Can someone explain how AIDs supports evolution?
Rapid adaption by mutation and natural selection of the virus. Take the viruses surface identification proteins. they change rapidly due to mutation and those that best avoid detection by the body go on to make copies of themselves. The very definition of evolution.
Which kind of mutation has greater potential to affect the evolution of a population Explain?
A frame-shift mutation has greater potential to affect the evolution of a population because it can alter the entire reading frame of a gene, leading to a non-functional protein. This can result in significant changes to an organism's phenotype, potentially affecting its survival and reproduction, and thereby influencing the population's evolution.

What are theories of mutation and natural selection in evolution?
The theory of mutation proposes that genetic variations occur randomly and are the driving force behind evolution. Natural selection, on the other hand, suggests that organisms with beneficial traits are more likely to survive and reproduce, leading to the prevalence of those traits in a population over time. Together, these theories explain how genetic diversity arises and how species adapt to their environment through the process of evolution.
Explain how a species can change over time?
Through mutations in DNA. If a mutation is beneficial and helps the organism survive it is passed on to the next generation which leads to the evolution of a species causing it to change.
Are there other theories that explain the same event as evolution theory?
No, there are no other theories but the theory of evolution by natural selection that explain so much about evolution.

Why was natural selection an important contribution to the theory of evolution?
Natural selection was important because it provided a mechanism to explain how evolution occurs. It operates by allowing individuals with advantageous traits to survive and reproduce, leading to the gradual accumulation of those traits in a population over time. This process helps to explain the diversity of life on Earth and how organisms have adapted to their environments.
What are the main mechanisms used by secular scientists to explain evolution?
All educated and not ideologically blinded scientists explain evolution by three primary mechanisms. Genetic drift, gene flow and natural selection.I have the feeling you do not know what secular means.
1 Do polymorphism and mutation explain the same biological phenomenon?
no polymorphism and mutation are different.polymorphism represents overall change in an organism whereas mutation may or may not bring overall change.
