Why is the chicken more closely related to the T. Rex as opposed to something like an Ostrich?

It’s not. They’re both equally closely related to the T. rex. Think of it like a family: you (chicken) and your sibling (ostrich) are both equally related to your cousin (T. rex). You both share a common ancestor (grandparents).

Well, it’s not so much that chickens are more closely related to T. Rex than ostriches are, but rather that ALL birds share a common ancestor with T. Rex. Birds are basically modern-day dinosaurs, so it’s like one big family reunion. Chickens just happen to preserve a lot of the traits that make that relationship easier to see. 練🍗

Ostriches, chickens, and *T. rex* are all descendants of dinosaurs, but *T. rex* is a different branch of dinosaur. Ostriches and chickens are both descendants of *archaeopteryx* or its relatives, making them “maniraptorans” (literally, “hand-thief”), dinosaurs that can fly. The *tyrannosauroidea* split from the ancestors of the *maniraptora* some 170-200 million years ago.

Like *all* modern birds, they are more closely related to *T. rex* than any non-bird species today is, but that’s like saying you are more closely related to giant sloths or woolly mammoths than any non-mammal species is. Of course you are! That doesn’t mean you’re *closely* related.

Because birds evolved from theropod dinosaurs like the T. Rex. Chickens inherited a lot of the same traits, while ostriches adapted differently over time. Feathers, skeletal structure, etc. basically make chickens tiny, clucking dinos. 練閭
