evolution through the ages:
Despite the belief that lizards are the closest the modern human kind can get to dinosaurs, the dinosaurs' closest relative are birds. Dinosaurs, similar to many organisms, create offspring through sexual reproduction and are thus able to inherit traits from their ancestors. Most dinosaurs, for example the Tyrannosaurus Rex walked with its limbs held upright and on their toes, similar to birds. Dinosaurs also had similar bone structure that is commonly found in many mammals and birds in the present day, including the long and curved neck, the ankle which is a joint only used for the back-and-forth motion and the femur bone which was straight and protruded out from the shaft and into the hip socket.
Birds are a direct descendent of dinosaurs. In 2005, Matt Harris and John Fallon while studying a mutant chicken in the University of Wisconsin had found sabreshaped formations almost identical to embryonic alligator teeth. However, the chick they were studying was a tiny bird due to delayed growth, likely from the mutation. In 2007, Hans Larsson, a palaeontologist at McGill University conducted an experiment for the evolution of long tails in birds. He studied embryonic stages of a chicken and while looking at a two-day-old chicken embryo he found it had 16 vertebrae reptilian tail, which became shorter until the chick hatched with only 5 vertebrae.
Even before the large asteroid hit Earth, eliminating most of the dinosaurs, the climate was already changing. Dinosaurs had evolved into birds to suit the environment better because of the lessening variety of plants due to the climate change. However, their blueprint still remains in the modern-day bird but will not surface because of the changing environment that is occurring again presently and in the near future.
