What is common descent in biology and how does it explain the evolutionary relationships between different species?

Common descent in biology is the idea that all living organisms share a common ancestor. This theory explains the evolutionary relationships between different species by suggesting that all organisms have evolved from a single common ancestor over time, leading to the diversity of life we see today. By studying similarities in DNA, anatomy, and other characteristics, scientists can trace the evolutionary history of species and understand how they are related to each other through a process of descent with modification.


What is branching descent?

The rise of two species from one species in a continuing process that resembles the branching of a tree or bush. This is called phylogenetic evolution and is the main driver of species arising over time.


Darwin believed that all organisms on Earth are united into a single tree of life by what?

Darwin believed that all organisms on Earth are united into a single tree of life through the process of descent with modification, where species evolve from common ancestors through natural selection. This concept implies that all living things share a common ancestry and have diversified into the many forms we see today.


What does evolution theory states?

The theory of evolution states that all species of organisms have descended from a common ancestor through a process of gradual change over long periods of time, driven by natural selection acting on heritable variations within populations. It explains the diversity of life on Earth and how species adapt to their environments.


What is members of a single species that occupy a common area form a called?

Members of a single species that occupy a common area form a population.
