    life forms that back then were primitive. The second is natural selection which that the entire complexity and intelligence of life has evolved by many small random mutations. These mutations help organisms survive in many different environments. The theory of intelligent design holds that certain features of the universe and of living things are best explained by an intelligent cause‚ not an undirected process such as natural selection. Through the study and analysis of a system’s components

    suggested by renowned Charles Darwin: heredity and natural selection. Heredity is the principle that organisms pass on different combinations of their traits to their offspring.

According to natural selection‚ the organisms with strong‚ "fit" traits are
