You can hear different theories and scholars views about Evolution.
It’s helpful to remind ourselves that
the word “evolution” is an accordion-word that can be expanded or
contracted to suit the occasion. The evolutionary biologist Francisco
Ayala points out that the word “evolution” can be used to mean at least
three different things:
1. The process of change and
diversification of living things over time. It is in this sense that
biologists say that evolution is a fact. But obviously this fact, so
stated, is innocuous and would not be disputed even by the most
fundamentalist Young Earth Creationist.
2. Reconstruction of evolutionary
history, showing how various lineages branched off from one another on
the universal tree of life.
3. The mechanisms which account for
evolutionary change. Darwin appealed to natural selection operating on
random variations in living things in order to explain the adaptedness
of organisms to their environment. With the development of modern
genetics, genetic mutations came to supplement the Darwinian mechanism
of natural selection by supplying an explanation for the variations on
which natural selection works. Accordingly, we can call this hypothesis
“neo-Darwinism.”
Now evolution in the senses of (2) and
(3) is not an established fact, despite what is said and believed in
popular culture. According to Ayala, “The second and third
issues—seeking to ascertain evolutionary history as well as to explain
how and why evolution takes place—are matters of active scientific
investigation. Some conclusions are well-established. Many matters are
less certain, others are conjectural, and still others. . . remain largely unknown” (Darwin and Intelligent Design).
