Dinosaurs are said to be the ancestors of birds. Why did these dinosaurs reduce in size, and develop wings? A new study has exposed the possible reasons and advantages of the consistent reduction in size of the ancestors of birds, the Theropod dinosaurs.
Dinosaurs come from birds, as evolutionists have theorised decades back. If this is really true, why did they evolve into birds, decreasing in size and bearing wings? In an attempt to categorising any pattern of evolution, scientists have studied the family trees of many species of dinosaurs. They examined around 1500 anatomical traits of the animals to determine their lineage. To understand how they might have evolved over time, the researchers made use of mathematical models.
Their results showed that the Theropod dinosaurs were the ones to have consistently transformed into smaller creatures over time. The Theropods are said to be the ancestors of birds. They are also said to have had feathers. Feathery dinosaurs? Yes, pretty much that. The theropods might have evolved these special traits like feathers faster than the other dinosaur species.
They were smaller, lighter, able to evolve at a faster pace, and hence, were at a great advantage over the other dinosaurs. They thus had more opportunities to exploit other ecosystems, like trees. They could climb onto trees, glide and fly away with just a click of the wings. They could fly away to new lands as well. Having a new, efficient means of transport, which was supported by their lighter weight compared to the majestic dinosaurs, they could have easily escaped the meteorite impact that is said to have killed most dinosaurs.
So, the Theropods changed for the better, or so it seems. Who says smaller size does not make one better?
