Do you think could Theropods evolved into birds? I think they could cause dinosaurs bones are more likely related to the birds, I can give you few examples: Large Orbits with the eyes opening in the skull, hollow thin-wallted bones,3-fingered opposable grasping manus (hand), 4-toed pes (foot); but supported by 3 main toes, and many more. So I watched a documentary about decoding dinosaurs and there was some thing that involved birds ( I can give you the documentary if you want and tell you at what moment of they video the thing is.) It's about a guy loking at a chicken embrion and when he locked at a 5 days old embrion he sought a tail like a velociraptor ( Of course not so many vertrebrates as a velociraptor but still enough.), I don't know if this is a clue that dinosaurs evolved in birds, what is your opinion about it? About dinosaurs ( Theropods.) evolving into birds.

Weishampel et al. (2004)'s cladogram puts Aves as a clade within the Theropoda, so based on what is generally accepted, they did. In the cladogram, it goes like this;
Theropoda > Tetanurae > Avetheropoda > Coelurosauria > Tyrannoraptora > Maniraptoriformes > Maniraptora > Paraves > Avialae
Deinonychosaurs are the closest extinct clade to extant avians, branching off from the same taxon as the Avialae.

I have found this family tree somewhere and I find it interesting, I am certain belive that dinosaurs evolved into birds, but I want to see or hear someones else opinion about this not just mine .
