Why can it be wrong to treat acquired traits as a permanent basis of evolution?
Answer and explanation
Correct answer: Because they generally do not change the hereditary information in gametes
An acquired trait develops during an individual’s lifetime because of use, training, environment, injury, or other experiences. For evolution, a variation must be heritable, meaning that relevant information must pass through reproductive cells to offspring. Many acquired body changes do not alter the DNA of gametes, so they are not directly inherited. Therefore they cannot normally serve as a permanent evolutionary basis by themselves.
