Welcome to life on earth. How do you think every creature in the history of the universe has found a mate? Do you suppose that the T-Rex's father negotiated with the other T-Rex family for their daughter, and worked out an appropriate dowry? Do you think early humans were all married off by parental or tribal arrangements? Do you suppose that young men and women (or young male animals and young female animals) never looked at each other and recognized (throught the mechanisms that nature herself has provided) that "this is the mate for me?"
Do you suppose that the peahen, carefully examing the brilliant display of 4 or 5 peacocks, isn't going to eventually "take a chance" on one of them -- for reasons only she knows?
Yes, you are right, you pays your money and you takes your chances. Welcome to life on earth.
