Homosexual orientation in males: evolutionary and ethological aspects.

Muscarella F, Fink B, Grammer K, Kirk-Smith M.

Journal Article 2001; 22(6): 393-400 PubMed PMID: 11781535 Keywords: Adaptation, Physiological, Biological Evolution, Brain:physiology, Culture, Homosexuality, Male:ethnology, Humans, Male, Neurosecretory Systems:physiology,.

: Evolutionary theory proposes that adaptive traits are reproduced more successfully than maladaptive traits. Accordingly, natural selection should favor heterosexuality as it facilitates reproduction and the propagation of genes. However, the question becomes, what has maintained homosexuality in a small but consistent percentage of th.....
