Evolution is weird like that Horse doesn't need a horn as it's already big enough and form herds to ward off predators and their kicks are already deadly enough as a defense mechanism and if that doesn't work outrun them. Also too tall to even use a Horn for defense and don't nee

Which one gives you an evolutionary advantage that can be passed down to your offsprings?

Well they did exist once... Sort of...

Adult one is 5-6 meters tall, but yea 12 meters neck

who said giraffes are real either?

Only one solution.

Nature doesn't give a shit what you believe.

and not the fish that has a long horn with a light on it ? we have crazier shit on this planet. like that pokemon shit Kabuto, that exist in real life.

Enjoy this 17th century illustration of a giraffe. Image receiving these illustrations from travelers who had visited distant lands. These animals all sound fake.

2 out of 3 confirmed aint bad!
