How closely related are humans to birds?

Humans and birds are a different matter. Yet they, too, share a lot of DNA — 65 percent. Understanding the similarities and differences between human and avian DNA is important.

Why are some birds unable to fly even though they have wings evidence?

Their wing bones are either missing or smaller for their body size than the wing bones of the tinamou. But they’re missing another bone called the keel bone, where flight muscles attach. Birds that can’t fly often also have bigger bodies and longer legs than birds that fly.

How various theories explain flight in birds?
