Sympatric Speciation
The evolution of numerous species, such as Darwin's finches from a single ancestor is called adaptive radiation.

An early ancestor of humans is called Australopithecus. This species is known for its upright posture and bipedal locomotion, and is considered an important transitional form in human evolution.
When two or more species sharing a common ancestor become more different over time, it is called divergent evolution. This process occurs as populations adapt to different environments or ecological niches, leading to variations in traits and behaviors. Divergent evolution can result in the formation of new species as these differences accumulate over generations.
Evolution is a change in species over time.
The principle that states all species have descended from a common ancestor is known as the theory of evolution. Proposed by Charles Darwin in the 19th century, this theory explains how populations change over time through the process of natural selection, leading to the diversity of life we see today.
The similarity of sheep and reindeer is due to parallel evolution. This is when two species have a common ancestor and have developed similar traits, despite living in different areas.
Convergent evolution. It occurs when different species independently evolve similar traits in response to similar environmental pressures, even though they do not share a common ancestor.
An early ancestor is often referred to as a "progenitor" or "ancestor." In the context of evolutionary biology, it can also be termed a "common ancestor," which is a species from which two or more descendant species evolved. Fossils or remains of these early ancestors help scientists understand the evolutionary history of organisms.
