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.

When the internal strucure of two species are very similar what can be inferred about both species?
They evolved from a common ancestor.
What does monophyletic group consist of?
A group of species that consists of a common ancestor and all of its descendants (also referred to as a clade).
What term is used to describe structures that come from a common ancestor?
A taxon of closely related species that share a recent common ancestor is a genus.
What best describes the theroy of evolution?
The theory of evolution explains how species change over time through natural selection, genetic variation, and adaptation to their environment. It is supported by evidence from various fields, such as paleontology, genetics, and biogeography, and is considered the central organizing principle of biology.
What supports the scientific theory that all species share a common ancestor?
Evolution.
What does the principle of common descent imply about humans?
Apes and humans descended from the same common ancestor.
What does it mean if species are said to have common ancestor?
If species are said to have a common ancestor, it means they are believed to have descended from a single, shared ancestor species in the past. This indicates that despite differences observed in the species today, they share a genetic and evolutionary heritage that links them back to a common origin.
What is a common ancestor?
a common ancestor is a species that multiple species share as the species they descended froma person born or that has lived before you and the word common means the same SO ....... its when you have the same descendant or person who lived before you or an ancestor that's the same

What does the main trunk at the bottom of a phylogenetic tree represent?
The main trunk at the bottom of a phylogenetic tree represents the common ancestor from which all the species or groups included in the tree descended. It is the starting point from which the branches representing different species or groups diverge.
The occurrence of the same blood protein in a group of species provides evidence that these species?
The occurrence of the same blood protein in a group of species suggests a common evolutionary heritage or a shared ancestry among those species. It is likely that these species inherited the blood protein from a common ancestor and have retained it through evolution. This shared presence of a specific blood protein can also indicate functional or adaptive significance in these species.
What are the relatives of a cheetah only?
The closest living species related to the cheetah are the cougar and the jaguarundi. All are descended from a common ancestor in North America.
What does it mean when two species share a common ancestor?
An ancestor.

Do people dissect chimpanzees?
We are not directly descended from chimpanzees, we share a common ancestor.
Are the chicken and the t-rex related?
Yes, they share a common ancestor. The group that contains the chicken, the T. rex, their common ancestor, and all the species that descended from that ancestor is called Coelurosauria.
