What is cladistics?
A system that groups organisms by ancestry
Living organisms on Earth share many common characteristics?
False
Why the homologous structures are evidence of evolutionary relationship?
They show similarities between organisms structure. if the similarities are large then it shows that those organisms share a common ancestor.
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 it say when humans and chimpanzees have similar DNA?
That they share a common ancestor.
What are Descendant organisms?

Does the theory that organisms share a common ancestor is known as common descent?
Yes, that is true.
What is cladistics?
A system that groups organisms by ancestry
Similar features in organisms that do not share a recent common ancestor are the result of what?
Similar features in organisms that do not share ancestry means both organisms adapted to their environment. They developed the features to survive.
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.
Do seals and humans share a common ancestor?
yes they do in facts share a common ancestor.
Is it rue that humans have not descended from chimpanzees but do have a common ancestor with them?
Yes, that's correct. Humans and chimpanzees share a common ancestor that lived several million years ago. While humans and chimpanzees have diverged along separate evolutionary paths since then, they still share a significant amount of genetic material due to their common ancestry.
Living organisms on Earth share many common characteristics?
False
Why the homologous structures are evidence of evolutionary relationship?
They show similarities between organisms structure. if the similarities are large then it shows that those organisms share a common ancestor.
What does it mean when two species share a common ancestor?
An ancestor.
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 dragons and vampires share a common ancestor?
