This tree, a member of the genus Celtis, grows in temperate climates.The hackberry seeds pictured here, roughly 50 million years old are some of the proofs that evolution never occurred. This plant has always existed as the hackberry and, like all other plant species, it has never gone through any intermediate stages. It is not descended from any other plant, and never developed into any other plant. In fact, evolutionists are well aware that there are no intermediate form fossils they can point to as evidence of plants" supposed evolution. George Gaylord Simpson, one of the founders of neo-Darwinism, states this fact thus: "This regular absence of transitional forms is not confined to mammals, but is an almost universal phenomenon, as has long been noted by paleontologists. It is true of almost all classes of animals, both vertebrate and invertebrate. . . it is true of the classes, and of the major animal phyla, and it is apparently also true of analogous categories of plants."
