What are Descendant organisms?
Descendant organisms are organisms that share many in common because they share a common ancestor.
Do dragons and vampires share a common ancestor?
There has been no evidence of such an ancestor.
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.
Does the theory that organisms share a common ancestor is known as common descent?
Yes, that is true.
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.
What is the evidence which shows that mollusks and annelids share a common ancestor?
Mollusks and segmented worms have a one-way digestive system, a separate mouth and anus, and their larvae are very similar. This is the best evidence that they have a common ancestor.
Do seals and humans share a common ancestor?
yes they do in facts share a common ancestor.
What is the best evidence that organisms of two different species share a common ancestor?
The best evidence that organisms of two different species share a common ancestor is the presence of homologous structures. These structures have similar features due to shared ancestry, even if they serve different functions in different species. Additionally, similarities in DNA sequences and developmental patterns can indicate a common evolutionary history.
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.
What evidence indicates that two big cats share a common ancestor?
Virtually everything about them, from their morphology to their embryological development to their behaviour to their genomes.
