What is the relativity of the utility and harmfulness of mutations? Give examples.

To understand evolutionary transformations, it is important to remember that mutations that are harmful in some conditions can increase viability in other environmental conditions. A mutation that causes underdevelopment or the complete absence of wings in insects is certainly harmful under ordinary conditions, and wingless individuals are quickly replaced by normal ones. But on oceanic islands and mountain passes, where strong winds blow, such insects have an advantage over individuals with normally developed wings.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
