God seems to have created species gradually over a period of many years. The fossil record in what's called the Cambrian layer shows that not all species were created during the same geological period. This led evolutionists to think one species turned into another over a period of time.
was complete when created but not all species are found were created at the same geological time.
Many people would be shocked to learn that leading proponents of evolutionism have junked the unscientific theory of gradual evolution that claims one species turns into another species over the course of thousands or millions of years. They don't give up on the term, however, but instead redefine it as "punctuated equilibrium," whereby one species turn into another in one iteration. Basically, a chicken lays an egg and a duckling is hatched, or a dog has a litter and a kitten comes out.
The theory, invented in 1972, became the accepted theory by 1980.
But as Newsweek reported in 1980,
that at a conference in Chicago that year,
The first fork in evolutionism is theistic vs. atheistic evolution. Atheistic evolution denies God created anything and is, therefore, rejected by Catholics. Theistic evolution, however, admits God created matter ex nihilo, out of nothing. It asserts this material then developed naturally into stars and planets. Pope Pius XII personally believed in a theistic form of the so-called Big Bang Theory that's not contrary to Genesis 1:3, which reads, "God said: 'Be light made.' And light was made."
Theistic evolution forks into cosmological and biological evolution. Cosmological evolution holds that only inorganic matter can naturally develop or evolve. Biological evolution, however, claims that even organic or living matter developed from inorganic material. It further asserts that simple life forms or species evolved through so-called macro-evolution, changing into different living species. Macro-evolution is distinct from micro-evolution, which merely explains how various breeds occur within the same species.
Biological evolution splits into materialist and spiritualist theories. Unlike the latter, materialistic evolution denies that God individually creates each human soul. In paragraph 36 of his 1950 encyclical Humani Generis, Pope Pius XII condemned this misconception: "[T]he Catholic faith obliges us to hold that souls are immediately created by God." In paragraph 37 of the same encyclical Pius XII also condemned the heresy of "polygenism," which claims man had many sets of original progenitors apart from Adam and Eve.
Macro-evolution divides into gradual evolution and so-called punctuated equilibrium. Gradual evolution professes that one species evolved into a different species gradually over many generations. Owing to the lack of any transitional fossils or any zoological examples undergoing such change, punctuated equilibrium proposes that one species evolved into another species in a single iteration. A dog giving birth to a cat is far-fetched but not heretical.
