When the internal strucure of two species are very similar what can be inferred about both species?
They evolved from a common ancestor.
What supports the scientific theory that all species share a common ancestor?
Evolution.
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 are some clues scientists use as evidencece for evolution?
DNA can be used to match two species and determine if they are related or share a common ancestor. In addition, the existence of DNA itself is proof for evolution on a large scale - virtually all organisms share the same nucleic acid as the genetic code, leading scientists to the conclusion that all species shared a common ancestor at one time.
What does it say when humans and chimpanzees have similar DNA?
That they share a common ancestor.
What does it mean when two species share a common ancestor?
An ancestor.
Are lions related to the hyenas?
They share a common, very distant 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 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 supports the scientific theory that all species share a common ancestor?
Evolution.
Why do related species share homologous traits?
Related species have inherited homologous traits from a common ancestor.
Do seals and humans share a common ancestor?
yes they do in facts share a common ancestor.
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 does a branch point in a cladogram represent?
The branch point in a cladogram represents a specific ancestor that is separated into two or more species. For example a leopard and a house cat share a common ancestor. A similar example is that a wolf shares a common ancestor with the leopard's and house cat's ancestor but the wolf's ancestor lived longer than the leopard's and house cat's ancestor. Scientists use something called cladistics to determine the one common ancestor that multiple species have in common.
Do toads come from frogs?
No. Although frogs & toads share a common ancestor, they are now classified as completely separate species.
What do the similarities between the skeletal structures of these four species most likely indicate about their evolutionary history?
These four species are distantly related and share a common ancestor.
Do dragons and vampires share a common ancestor?
There has been no evidence of such an ancestor.
