Their body mass is too large for their wingspan and wing muscles, and they have evolved in such a way that they no longer posses the innate knowledge of how to fly. Their wing muscles cant support their weight.That is why they cannot fly.
Their bodies are too heavy, and their wings are too small.
Evolutionarily, because they don't need to fly. They need to run. they also evolved from
Flightless Birds. tanner eno likes chelsey seiger
An ostrich cannot fly simply because the wings only represent a passed down trait from its previous generation, or may I say previous evolution of species of the bird. Its the same reason why humans have a tailbone but no tail. It is useless to us, but was used by our predecessors, the primates. tmj
