We see constant reminders of bringing back the dinosaurs. There is a misconception of what that actually means in real terms. If you reverse the evolution process, then you can only get the original version and not any version that you want. A chicken will not produce both a tyrannosaurs and a triceratops by example. Reverse engineering will only produce the dinosaur that evolved into the specific bird being used.

If a scientist decided to manipulate DNA to create a dinosaur from scratch it is unlikely to yield the accurate results that have happened naturally. This, in the extreme, is very unlikely to ever happen! Equally difficult, would be for a scientist to obtain actual DNA, unpolluted, from dinosaur remains and piece them together to create the unadulterated true version. Unless, of course, the dinosaur was an asexual reproducer. Otherwise, they would need to obtain two separate genomes and combine them into an egg stripped of its DNA content for recombination. What most of these scientific articles refer to when they say return of the dinosaurs, like this one [here] is that traits will be produced that resemble the dinosaurs in general.

We need to remind ourselves that birds have evolved into many species since the dinosaurs went extinct and there is no way of actually telling which specific dinosaur was the predecessor of birds in general. It should go without saying, that not every biped dinosaur must have evolved feathers and flight. More likely it was a specific group of dinosaurs and probably did not include the family of dinosaurs that already flew. This is what the evidence actually suggest. There are actual fossils of feathered dinosaurs found in China.

What do these scientists actually mean by dinosaurs? They mean that they can tweak out features that the predecessors of birds had in general terms. They can cause a dinosaur tail to grow on a chicken and alter the legs into dinosaur looking legs by changing the development of the embryo with DNA manipulation. These are the current hopes anyway. It will be considered a work of wonder, something to marvel at, and a starting point for greater things to come in DNA manipulation.

I have no doubt that someday, step by mighty step, man will be able to reproduce the original dinosaur from whence the chicken evolved. This will not create dinosaurs of every type and size that originally existed and roamed the earth.
