Much too general a statement to bear significance (some animals mate for life--swans, for example). And animals most certain choose sexual partners...just think of all the odd mating rituals males of many species go through to win a sexual partner.
Whether animals have "emotions" (depending on how the term "emotion" is defined) is completely independent of how human may or may not think of animals.
And as to emotions, your 1970's psych book has been profoundly outdated by more recent work that relates emotional sensation and thought to brain chemistry and electrical activity which is measurable by MRI and PET scans.
And BTW I know some humans (many actually) who are definitely NOT above animals. Funny thing that...they are all Liberals.
Hey my FRiend, if you want to believe that Swans use the same emotions picking a mate as you do, you be my guest. But seriously, they are not picking a mate, they are picking their right to procreate.
However, I’ll tell you this, because you can use your fingers to type, you are more intelligent than any of them. Including the liberals. Don’t belittle yourself.
