у слонов 45% всех половых актов гомосексуальны
у жирафов до 90% всех половых актов гомосексуальны
у дельфинов - 40%
у львов 8%
шимпанзе иерархические - 15%
бонобо - 55%

как видно бонобо это не самое гомосексуальное животное.

на гомосексуальное поведение изучено более 1000 видов млекопитающихся, птиц и насекомых

Общий вывод практически всех ученых , занимающихся проблемой "зачем животным гомосексуализм" - это сильно снижает конкуренцию между самцами в стаде, способствуя сплоченности коллектива. Особенно верно это для жирафов, дельфинов и всех шимпанзе (и для человека).
