What similarities in development lead scientists to infer turtles chickens and rats share a common ancestor?
They look similar at birth
What is the evolutionary ancestor ancestor to the fungi?
Scientists have not identified an evolutionary ancestor to fungi.
Why do humans and chicks develop similarly to reptiles?
because of a common ancestor of all vertebrates in Pre-Cambrian period, scientists says that they all will have a common development stage.
How does comparing physiological similarities of living species provide evidence of?
Physiological similarities suggest the species evolved from the same ancestor.
How can you use classification to tell how closely organisms are related?
Scientists mainly compare similarities and differences in what the organisms look like. With the less obvious relations, they analyze their DNA. The goal is to find a common ancestor between the two organisms. The more recently that ancestor existed, the more closely related the organisms are.
Why do scientist think related species have similar body structures and development patterns?
Why do scientists think related species have similar body structures and development patterns?
Why do scientists think arthropod and semented worms have a common ancestor?
Scientists believe this because they have a similar body model.
How could two species that evolved on different continents have many similarities?
A common ancestor.
What does the similarities between humans and dolphins cats and bats in indicate?
that they share a common 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.
What difference did scientists discover between today's whales and fossils of their ancestors and how does this show whales and animals with four legs probably descended from a common ancestor?
Bones of whale ancestors showed that whales had hip bones along with legs and hind feet.
What are the similarities of human and chicken embryo?
Mammals, birds, and reptiles all derive from a single common ancestor.
