Why do some biologists refer to homosexuality as an evolutionary puzzle? Group of answer choices Because it is a question that is exciting and tricky to answer. Because homosexuality only recently evolved. It was not present in older populations of humans. Because a trait that is caused by environmental factors should not be maintained in populations over time. Because a genetic trait that leads to lower reproductive success should not exist at high frequencies.

Based on the analysis provided by the evolutionary psychologist, Dr. Barash, among the alternative leading theories providing an explanation for the biological continuation of homosexuality in human evolution, identify the theory proposing that homosexuality could be a trait of successful alloparents, a trait that would contribute to the overall well-being of the offspring of the entire group. Select one: A. Social Prestige B. Balanced Polymorphisms C. Sexually antagonistic selection D. Kin selection E. Group selection
