Evolutionists determine that two organisms have a common ancestor is by looking at fossil evidence in different rock layers using the law of Superposition (Oldest layers are on the bottom, newest are on the top) and compare the skulls or other bones to each other in order of oldest to newest (or newest to oldest). Another way to determine this is to examine the amount of DNA a certain species shares with another species. An example of this would be that Humans share roughly 90% of our DNA with chimpanzees or the other Great Apes.

What are clades A clade is a group of organisms consisting of a common ancestor and all its descendants But doesn't every living thing have a common ancestor Please help Thanks?
Yes, all living things are just groups of organisms consisting of common ancestors and all their decendant's. Clades is just a word that means a group of organisms.
What does it mean for species to have an evolutionary relationship?
If two organisms share an evolutionary relationship, that means that they have a common ancestor on the evolutionary tree. The more recently the shared common ancestor lived, the more closely related the two present organisms are, evolutionarily.
Do organisms evolve slowly over time and can two different organisms have a common ancestor?
Yes they evolve slowly over time and a panda and raccoon have common ancestors.
What is the mating of two closely related individuals?
Organisms sharing a common ancestor are of common descent. The LUA , the last universal ancestor, lived 3.9 billion years ago.
Humans and gorillas have one different amino acid in their hemoglobin sequence. What does this say about the evolution of these two species?
Answer this question… They probably have a recent common ancestor.
How would you know if organisms shared a common ancestor?
Scientists can determine if organisms share a common ancestor by analyzing their genetic and morphological similarities. The more similarities that exist, the more likely it is that they share a common ancestor. Additionally, the study of evolutionary relationships through techniques like phylogenetic analysis helps to trace back common ancestry among organisms.
What are Descendant organisms?
Descendant organisms are organisms that share many in common because they share a common ancestor.
Which organisms have possible common ancestor?
All of them
What does the presence of Similar genes in very dissimilar organisms imply?
The presence of similar genes in very dissimilar organisms implies a common ancestor. This suggests that these organisms share a common evolutionary history and have inherited these genes from a common ancestor. The concept is known as homology.
What is derived characteristic?
A derived character is a trait that is shared by organisms with a recent common ancestor. It is also called as shared character.
What is the definition of ancestral trait?
An ancestral trait is a trait that is shared by a group of organisms and their common ancestor. It is a characteristic that has been inherited from a common ancestor and has been passed down through generations without change.
Does the theory that organisms share a common ancestor is known as common descent?
Yes, that is true.
What is an evolutionary?
If two organisms share an evolutionary relationship, that means that they have a common ancestor on the evolutionary tree. The more recently the shared common ancestor lived, the more closely related the two present organisms are, evolutionarily.
How do embryo help identify a common ancestor of different organisms?
we compared their bone.
How embryos help identify a common ancestor of different organisms?
we compared their bone.
How do evolutionists try to use the classification system to reinforce their worldview?
Evolutionists use the classification system to show the hierarchical relationships between organisms, highlighting the shared ancestry and evolutionary history among different species. By showcasing how organisms are grouped based on their shared characteristics, evolutionists argue that this classification system provides evidence for common descent and the process of evolution.
What do evolutionists say about evolution?
Evolutionists study and accept the scientific theory of evolution, which explains how organisms change over time through natural selection and genetic variation. They believe that all living organisms share a common ancestor and that evolution is driven by processes such as mutation, gene flow, and genetic drift. Evolutionists view the fossil record, comparative anatomy, and molecular evidence as supporting evolution as the best explanation for the diversity of life on Earth.
