As per Darwin’s theory, only the superior changes are naturally selected and the inferior ones are eliminated. Thus, not all the adaptations contribute to a progressive evolution. For example, people living in tropical countries have more melanin in their body to protect them from the sunlight.
Almost all organisms share common ancestry with some organism. According to Darwin, all organisms had one common ancestor at some point in time and kept on diverging ever since. His evolutionary theories support the convergent theory and divergent theory of evolution with examples.
He had studied the birds at Galapagos Island which were later called Darwin’s finches. These birds developed different beaks as per the food availability. This showed adaptive radiation. Similarly, he also observed the Australian Marsupials which showed a number of marsupials emerging from an ancestor.
According to Charles Darwin, evolution is a very slow and gradual process. He believed that evolution took place over a very long period of time. When we talk about the time period in evolution we usually refer to billions of years. The generation of a species from another takes a long period of time. It is a very steady process as the changes and adaptation take a long time to stabilize and give rise to a new species.
