It is commonly known that dinosaurs went extinct because of the meteorite/asteroid that hit Earth. But some of them survived. The creatures that survived the crash, in the present, we call them birds. When the meteorite hit Earth, birds developed adaptations. They ate seeds, so when the fires burned up the forests, they were able to live on. Also, birds were fast, which helped them avoid getting killed by fires. Unlike most other dinosaurs, they are big and heavy.
Scientists also researched and investigated them. Birds can use tools and solve problems. Scientists used T. rex fossils to compare them with bird brains; turns out, they’re alike. There’s other evidence too. A quail has a trait, a hip, that resembles that of the T. rex and other dinosaurs. Also, chicks, even in the egg, grow teeth.
