I was shock after reading what I just browsed. Yes indeed, I thought bisexuality matters only are present to humanity, but yes also for different kind of animal species. In fact studies shown that same-sex couplings are common and well-known in the animal kingdom. The scientists have seen such same-sex going on in both male and female and even old and young. Aside from that they also find it in social and solitary creatures and also on branches of the evolutionary tree from insects to mammals.
However, unlike the human being, animals cannot be designated as gay or straight. Researchers explained that animals which are engaged in same sex flirtation or for partnership doesn’t mean for spurn heterosexual encounters. The activity is in fact normal to their society. Most of the reasons why they engage to same-sex activity according to the studies are to diffuse from social tensions, protect their young ones and generally because they find that it gives them fun. Others think that animals or insects can be compared to robots but scientists believe that just like human beings, animals as well have feelings and they are responding to it whatever they may feel.
