This article went very in depth
on both sides of the argument. I am agreeing with the fact of dinosaurs
evolving into birds for this essay. This is because I feel like better, more
believable points were made on the affirmative side of the argument. These
points were centered on how both birds like dinosaurs lay eggs, the many
homologous structure that they have in common, and closely related fossils that
have been found.
In this article, similarities in
bone structure between the first birds and dinosaurs were greatly emphasized.
Structures such as thin-walled bones, S-shaped neck, and many others are
mentioned. A fossil was found in 1860 that was “The London Specimen of Archaeopteryx
lithographica” this was an example of “Transitional form” (transition between
birds and reptiles). This shows that there could be a link between birds and a
certain type of dinosaurs. Birds also have many obvious similarities, such as
the fact that they lay eggs, have scales on their feet, and though it is not
visible it has been proven that their anatomy is very similar to dinosaurs.
This transformation could have
easily have happened through natural selection. When the dinosaurs were existent
it is proven that some did have wing like structures. If when the dinosaurs were wiped out, some
could have had a favorable trait that let them survive (possibly wings) and
passed this on to their offspring then it is possible that they could have
survived. They could also have possibly adapted through natural as the history
of the earth progressed into the bird today. This is also supported by the “transitional
structure” fossil that was found.
Overall I feel as though the
fact of birds evolving from dinosaurs is not a farfetched as it seems. Through
natural selection and many other processes of adaptation, it seems that
organisms find ways to survive. This is why I feel that it is possible for dinosaurs
to evolve into something altogether different to survive.
