Not always.
there are two types of mutations, A Good mutation or a bad one.
A bad mutation will happen very rarely but could still happen, The chances are almost to none
But there are also good mutations, The chances of getting a good mutation are 0.001
When mutations happen, And its bad, For an example a Cell If it gets a bad mutation, It will most likely not be able to compete with other cells for resources.
But if the mutation is "Good" The DNA which is a genetic code will be changed to have the good mutation put it.
A good mutation for a bacteria would be antibiotic resistance.
Bacteria Reproduce every 20 Minutes by dividing, So on a petri dish having the bacteria lay there for 24 hours, would have More than millions of Bacteria on it.
And in those moments of reproducing a Good or bad mutation WILL happen.
When you use hand sanitiser you kill germs right? But hand sanitiser says 99.99%, The .001% that lives has a good mutation that makes is be Resistant to antibiotics

It produces new varieties .

Is evolution good or bad?
Genetic mutations can be good or bad, but evolution refers specifically to those mutations that make an organism better able to survive and to perpetuate their species, which makes them generally a good thing.
What are some good mutations?
birds with really thin bones
What can cause changes in DNA sequences?
mutations
Are mutations good or bad thing?
They can be both good and bad depending on the mutation. Having extra arms may be a good thing if you are an alien, but being someone with extra arms can also be a bad thing. If you are not an alien, having extra arms might not be so grand. Do normal people have extra arms? If you are a person that got offended by this, i am so truly sorry. Bye:)
Changes in DNA are called mutations?
the answer is mutations.......................
How can embryology show that organisms are related?
It can be a good indication because mutations affecting embryos are especially detrimental, and so such mutations accumulate less over time.
Why do mutations that occur in the skin or nervous system tend to have little effect on the evolution of a species?
Most mutations that occur have a neutral effect, or none at all, so they would not affect evolution. Organisms with mutations that cause detrimental impact typically will not survive; therefore, they will not reproduce, and the mutation will not be passed on, so the species will not be affected overall. Beneficial mutations are typically the only mutations that will affect an organism's posterity and the evolution of its species, but good mutations are very rare. This is why most mutations have little effect on the evolution of a species.
