Several in cause. It could be as simple as a copying error during replication, a thymine dimer in a skin cell's DNA due to UV light, or a carcinogenic mutation of a cell's DNA as a precursor to cancer.

Mutations in DNA are caused by physical or chemical agents called mutagens. Physical mutagens include X-rays or UV light, which cause thymine dimers in DNA. Chemical mutagens can disrupt DNA in many different ways: incorrectly pairing bases during DNA replication, distorting the double helix of DNA, or chemically changing bases so that they have different pairing properties.

There are two main factors that cause a mutation in DNA. These factors include: the DNA fails to accurately copy itself and external influence cause a breakdown in the DNA.

Mutations can occur from endogenous or exogenous factors or from errors. Translocation, insertion and deletion are examples of factors that cause genetic mutations.

What is the most likely example of a favorable mutation?

A mutation that makes a rabbit able to run faster.


Can genes change throughout their lifetime?

Sometimes but not likely. When this happens it is most likely mutation.


DNA can result in dysfunctional protein production?

yes but it would most likely be unnoticable


Could a single mutation cause barbules to form on feather barbs?

Although the cause of barbules to form on feather barbs doesn't sound like a difficult change in evolution, it would likely take more than just a single mutation for such an evolutionary change to occur. Most likely, it would take many mutations.


When are behaviors most likely to occur?
