Placentals (e.g. humans) are mammals whose young develop internally, in their mother’s womb, nourished through a placenta. Marsupials (e.g. kangaroos) are mammals that carry and suckle their young externally in a pouch. According to the theory of evolution, placentals and marsupials evolved from a common ancestor that looked a bit like a modern shrew. These early placentals and marsupials allegedly then evolved into many different animals. What is so difficult for evolutionists to explain, however, is why, in so many cases, placentals evolved almost identical forms to marsupials (see fig. 6).
Many plants produce food and grow using energy from the sun, through a complex process called ‘photosynthesis’. One form of this is named ‘C4 photosynthesis’ and is particularly complex. Because of the differences between the plants that use the C4 process, evolutionists again have to argue that this evolved independently more than thirty times.13,14 It seems mind-boggling that a process of such complexity could have evolved once; but to claim that this happened so many times stretches credibility beyond all reason. It requires a lot of blind faith to be an evolutionist!
Also, sometimes structures alleged to be homologies must be explained away as homoplasies when the evolutionary family tree is changed. For example, based on supposedly homologous features in their skulls and teeth, whales were dogmatically proclaimed to have evolved from mesonychids, an extinct type of large predatory ungulate (animal with hooves). But DNA similarities convinced evolutionists that they evolved from another group—artiodactyls (‘even-toed’ ungulates), similar to the hippopotamus. So these supposedly definitive homologies must be re-interpreted as homoplasies.
