Atheism is unreasonable

Evolution has been observed in nature and in the lab.

Really? When has the reptile-bird transformation ever been observed?

Look, it's a crockoduck, or a reptobird, or perhaps a beaverbat? No it's a platypus:

The platypus represents the earliest offshoot of the mammalian lineage some 166 million years ago from primitive ancestors that had features of both mammals and reptiles. "What is unique about the platypus is that it has retained a large overlap between two very different classifications, while later mammals lost the features of reptiles," says Wes Warren, Ph.D., an assistant professor of genetics, who led the project.

It's all there in the DNA:

As part of their analysis, the researchers compared the platypus genome with genomes of the human, mouse, dog, opossum and chicken. They found that the platypus shares 82 percent of its genes with these animals. . . .
The researchers also found genes that support egg laying - a feature of reptiles - as well as lactation - a characteristic of all mammals. Interestingly, the platypus lack nipples, so its young nurse through the abdominal skin.

. . . When they analyzed the genetic sequences responsible for venom production in the male platypus, they found it arose from duplications in a group of genes that evolved from ancestral reptile genomes. Amazingly, duplications in the same genes appear to have evolved independently in venomous reptiles.

Notice however, that the platypus is not an example of a reptile becoming a bird, that didn't happen (dinosaurs are not reptiles). It is, however an early mammal very closely related to birds and reptiles and sharing a number a characteristics with them including egg laying.
