Freak of nature

Every reference to man is in the tone of superiority, the rest being lower or not as smart as man. Why alone has our brain been allowed by nature to grow so fast? It cant be Darwin alone since we’ve been around for an iota of a second across the panels of time. Are we nothing but a freak of nature, the bad apple in the basket which we havent turn a blind eye to hoping what we cant see, must not be true?
