the table compares key features of modern birds and archaeopteryx.
feature archaeopteryx observation modern bird observation
teeth had small teeth for catching food no teeth has a beak instead
hollow bones had lightweight bones to help it fly has lightweight bones for flying
tail shape had a long, bony tail for balance has a short tail that helps with flying
which feature shows that modern birds came from archaeopteryx?
both have teeth, which help them catch their food.
both have hollow bones, making them light for flight.
both have long tails, which help them stay balanced.
both have beaks, which help them eat different foods.

Explanation:

We look for a shared characteristic between Archaeopteryx and modern - birds as evidence of evolution. Archaeopteryx had lightweight bones for flying and modern birds also have lightweight bones for flying. This is a key feature indicating a possible evolutionary link. Modern birds don't have teeth, Archaeopteryx did. Modern birds have short tails, Archaeopteryx had long bony tails. And modern birds have beaks while Archaeopteryx had teeth.

Answer:

Both have hollow bones, making them light for flight.
