This had happened as a part of divergent evolution. It was explained by Darwin.

Divergent evolution occurs when two different species share a common ancestor but have different characteristics from one another. This is probably the type of evolution that first comes to mind when the topic of evolution comes up. After all, evolutionary theory teaches us that every form of life on Earth today developed from the first living cells! Over time, the original cells took vastly different paths of development and ultimately created the diversity of life on Earth—from trees to humans.

Divergent evolution occurs when a group from a specific population develops into a new species. In order to adapt to various environmental conditions, the two groups develop into distinct species due to differences in the demands driven by the environmental circumstances.

Darwin's finches are a good example of this. Darwin's finches are a group of about 15 different species of finches that live on the Galapagos Islands. Each separate species of finch adapted to a different diet, causing variation in their beak shape and/or size. All of them evolved from one species of finch that was a common ancestor.
