Ok, I'm really confused on this. If reptiles evolved into birds, and lizards evolved into snakes..then how?... Do you know what I mean? How would it be possible for them to evolve into BOTH?
Thanks.
Three words: Branching, branching, and branching.
You can't understand evolution unless you understand branching.
In any species, at any time, two populations can get separated from each other. If this happens, then
âTogether (the teeth) formed a sort of rosette that interlocked when the jaws were closed,â he added, saying that they might have been used in âthreatening displays" and for catching fish.
Martill and colleague David Unwin of the University of Leicester made the discovery after analyzing a fragmentary, yet toothy, fossil housed within the collections of the Natural History Museum, London.
The fossil was unearthed from the Cretaceous Cambridge Greensand of eastern England, revealing that the pterosaur lived around 100 million years ago during what is known as the Albian stage.
During that time, Cambridge was under the sea. But Martill said there might have been a low island to the south where London is now. The climate was tropical then. Based on other fossil finds, the region was teaming with life. Fish, ichthyosaurs, plesiosaurs, crocodiles, turtles, dinosaurs (including prehistoric birds), and different types of pterosaurs all lived in the area.
BIRD EVOLUTION AND ADAPTATIONS:- Beginning with Archaeopteryx, this video looks at the emergence and adaptations of birds. Feathers from modified ...
Archaeopteryx, the oldest known bird, lived 150 million years ago and is in many respects no different from flying birds living today. Evolutionists suggest that Shenzhouraptor sinensis was a transitional form that was able to fly and possessed both bird and dinosaur characteristics. “The evolution of birds”, like other claims made by Darwinism, is no more scientific than a fairy tale....

'Heirloom lice' help track rise of mammals, birds even have been the first animals to have lice, Johnson said. Reptiles have no hair or feathers onto which a louse could latch, but lice might have lived on the first feathered dinosaurs, then continued to do so as those dinosaurs evolved into birds. |

Love on the Rocks
Their isolation - 1000km off the coast of Ecuador - has meant many species have taken a unique evolutionary path on the Galapagos: 95% of the reptiles, 50% of the birds, 80% of the insects and 20% of the fish exist nowhere else.

They then applied the technique to fossils from plant-eating and carnivorous dinosaurs, flying reptiles called pterosaurs, and ancestral birds. The measurements revealed that the big plant-eating dinosaurs were active day and night, probably because
