Abiogenesis – There are no experiments which shows that if we add certain organic molecules like ammonia or methane into water they will transform into a living cell. A biologist named Richard Lenski took commonly found bacteria called E.Coli bacteria, separated them into twelve flasks and observed their replication for two decades. There were some genetic changes observed in the later generations of bacteria over a period of two decades but all of them remained bacteria.
Theory of homology – Genetic adaptation and mutation have proven to have fixed limits. Micro-evolution is a well-established scientific fact in the field of biology. Slight adaptations like shorter elephant tusks, bigger spots on the skin of a fish or larger heads of lizards due to change in environment is hardly a “proof” for major changes in anatomy, physiology and biochemistry of animals needed to transform them into animals belonging to a different phylum. Animals share very similar organ systems like respiratory, circulatory and digestive system and so evolutionary biologists have concluded that homology between animals represent evolution from a common ancestor. Well, one can argue that homology between animals can also represent a common Creator.
Artificial Selection (Breeding) – Hundreds of different kinds of dogs have been produced via artificial selection/breeding. But through this process they all still remain dogs. They do not change into leopards or elephants or some other form of animal.
Fossil Evidence – Where are the billions of missing links in the evolutionary chain. Rather than all life branching from a single organism, The Cambrian Explosion has revealed a forest of life from the very beginning. This sudden appearance of most major complex animal groups at the same low level of the fossil record is still an embarrassment to evolutionists.
Natural Selection – Selection begins with the projection of volitional selective capacity onto nature to do something like “favour” or “weed out” organisms. Scientists should find this unsettling. While some religious practitioners ascribe free-will to inanimate things, how can selection ever legitimately be applied scientifically, to an immaterial concept or to mindless entities? Before Darwin, the ability to choose was largely confined to designing intelligences, that is, to conscious agents that could reflect deliberatively on the possible consequences of their choices. Only intelligent beings can make choices and decisions.
