Final answer:
Europeans generally lack aggregated melanosome complexes, which are characteristic of groups with darker skin pigmentation evolved in high UV radiation environments.
Step-by-step explanation:
The population that does not have aggregated melanosome complexes among the choices given is Europeans. Aggregated melanosome complexes are a trait typically found in populations with darker skin pigmentation. These complexes are more common in populations that are heavily exposed to UV radiation as a natural adaptation to their environment, which is less applicable to Europeans who evolved in environments with less UV radiation. Therefore, both Far East Asians and American Indians may show variation in melanosome distribution within their populations, but Europeans are the group typically noted for lacking these complexes.
