Not all mutations are harmful. The improvements in creatures through evolution are from beneficial mutations. The beneficial mutations increase the creature's chance of survival and passing along those new beneficial genes to its offspring.

∙ 12y agoA mutation is a random change in genetic code.
The genetic code is very complex and has evolved to the present state over many millions of years.
A random change to anything that is so complex is far more likely to be harmful than neutral or helpful.

How does natural selection and evolution change species?
Mutations are believed by many evolutionists to provide a means for variablity in some of the characteristics of a species. For example, extra fingers and toes. However, since all mutations are DNA-destructive and result in a loss of information, increasing complexity from mutations is believed by many to be impossible. This is especially true if one subscribes to Information Theory, which states that information only comes from greater pre-existing information. Extra fingers only demonstrate an error in creating the correct number of digits, not additional information. If a certain variation provides an advantage for an individual (or inter-breeding group) they these individuals will survive and breed where all others will die. This is natural selection (not evolution). The offspring of the survivors will all carry the traits of their parents. Therefore, the fittest will tend to thrive, but not change into a different species, at least not through this mechanism.
When gaseous molecules are compressed they tend to?
They tend to change density, temperature or energy.
What nonmetals in the solid state are poor conductors of heat tend to?
Nonmetals in the solid state tend to be brittle and poor conductors of heat.
What do nimbostratus clouds look like?
Clouds that include the term "nimbus" tend to be the ones that come with moderate precipitation and storms. These clouds tend to be fluffy with dark gray bottoms.
What happens to gases as they are heated or cooled?
they tend to vibrate
How is albino squirrel a harmful trait?
Albinos tend to have awful eyesight.
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.
Is rust in your dishwasher harmful?
No, rust is not harmful. However, it's not helpful, either. And, if your dishwasher's racks are the source of the rust, they may need replacing, or you may want to consider replacing the dishwasher entirely (racks tend to cost around $100-150 each). Consider a model with nylon racks if replacing the entire dishwasher.
Is a lion helpful yes or no?
Lions are helpful in nature because they tend to "weed out" old, sick, or wounded animals and consume them as their prey.
Can some DNA mutations be beneficial to an organism?
Gene mutations may have positive or negative effects. Without "positive" gene mutations, a species would not be able to improve itself over time, in order to make it more it more adaptable to its environment. "Negative" gene mutations, by their very nature and definition, tend not to be able to survive in their environment.
What are some benefits of mutations to DNA?
Mutations allow new versions of DNA combinations to occur. These can be harmful, benign or beneficial. If they are harmful, they tend to be self eliminating, unless they only show up after breeding age. If they are benign, they may not influence the species. If they are beneficial, they create improved varieties of the organisms, resulting in greater diversity and therfore greater adaptability in the species.
Why are Caucasians are more likely to get progeria?
Insular communities tend to get certain diseases more. It can be because of religion, heritage, or inbreeding as well since if there are mutations and people only marry others with the same mutations, then they would be more likely to have children with whatever condition.
Why were Egypt naturals borders helpful?
They were helpful because it helped Egypt protect it's land from enimies, intruders, and also other tribes or warriors who might tend to rule Egypt.
Do the drive-through car washing services use harmful chemicals on my car?

try a cook book those tend to be pretty helpful when cooking
How are cicadas dangerous to humans?
Cicadas are not dangerous nor harmful to humans however they are very noisy and tend to eat certain plants.
Methods of growing or harvesting of computers?
They are self-replicating and reproduce best in captivity, spawning a new generation at ever-accelerating rates of speed. When captured in the wild they tend to be sterile. Mutations are common.
