One classical criticism of the theory of evolution by natural selection was the paucity of transitional species. However, Archaeopteryx is such a species. In what ways did it resemble its dinosaur predecessors? In what ways was it like or unlike modern birds?

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".
