Question

which of the following is not one of the mentioned factors that plays a role in how species change over time?
acquired traits
mutation
genetic drift
migration
rewatch

Explanation:

In the context of evolution (how species change over time), mutation, genetic drift, and migration are recognized as factors (mutation introduces genetic variation, genetic drift is random change in allele frequencies, migration is gene flow). Acquired traits, as proposed by Lamarck, are not passed on to offspring in the way needed for species - wide change over time (modern evolutionary theory shows that only heritable genetic changes matter, not acquired traits during an organism's lifetime).

Answer:

A. Acquired traits
