Question

Mutations _____.

cannot be caused by the environment
are the main sources of microevolution
can be discovered through genetic testing
are always harmful to an organism

--------------------------------------------------------

Can a mutation be beneficial to an organism?

No. Any change to existing DNA is harmful.
No. because mutations are caused by exposure to harmful radiation.
Yes. The benefit of a mutation can help it survive in a particular environment.
Yes. A mutation can give an organism what it needs to survive.

--------------------------------------------------

result from evolution in a similar environment
indicate a common ancestor exists between two organisms
are features which organisms still have, but no longer use
develop when a mutation occurs in the DNA of an organism
------------------------

Humans are at the top of the evolutionary ladder because we have the largest brains.
Any type of change in the shape or behavior of an organism is considered an evolution.
