∙ 11y agoThe term associated with the single-celled ancestor theory is "Last Universal Common Ancestor" (LUCA). This theory postulates that all living organisms on Earth trace back to a single-celled organism from which all life evolved.
Darwin's theory of common descent states that all organisms _____.
Darwin's theory of common descent states that all organisms evolved from past organisms.
The theory of Common Descentbelievesthat all species on earth have a common ancestor.
Common descent with modification is the concept that all organisms on Earth are descended from a common ancestor, and that over time, through the process of natural selection, genetic changes accumulate in populations leading to the diversity of life we see today. This idea was proposed by Charles Darwin in his theory of evolution.
Darwin believed that all organisms on Earth are united into a single tree of life by descent with modification, meaning that all living organisms share a common ancestor and have evolved over time through natural selection. This concept forms the basis of evolutionary theory.

The type of descent that explains why all species are linked in a single tree of life is called common descent. This theory proposes that all living organisms on Earth share a common ancestor, leading to the diverse array of life forms we see today. It is supported by various lines of evidence, such as genetic similarities and the fossil record.
The theory that states organisms evolved from a common ancestor is the theory of evolution proposed by Charles Darwin in his book "On the Origin of Species" published in 1859. Darwin's theory of evolution by natural selection explains how species change over time through the process of adaptation to their environments.
