The occurrence of the same blood protein in a group of species provides evidence that these species?
descended from a common ancestor
How does comparing physiological similarities of living species provide evidence of?
Physiological similarities suggest the species evolved from the same ancestor.
How do scientists use similarities in early development as evidence for evolution?
By examining fossils and by determining their relative and absolute ages, scientists have collected evidence that supports the theory that species changed over time.
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.
What does similar structures in embryos mean?
the species come from a common ancestor
What Different types of Evidence used when comparing plant species?
Physiological similarities suggest the species evolved from the same ancestor.
What supports the scientific theory that all species share a common ancestor?
Evolution.
The observation by Darwin that finches belonging to different species on the Galapagos Islands have many similar physical characteristics supports the conclusion that these finches?
originated from a common ancestor
The occurrence of the same blood protein in a group of species provides evidence that these species?
descended from a common ancestor
How does comparing physiological similarities of living species provide evidence of?
Physiological similarities suggest the species evolved from the same ancestor.
Why do you think the domestic dog is an ancestor of the gray wolf?
The genetic evidence is quite clear on this question. With great certainty we can say the domestic dog has only the gray wolf as ancestor.
Similarity of structure of the forelimb of a bird and a mammal is an example of what evidence?
Homologous structures - the forelimb structures are anatomically similar and were derived from a common ancestor; however, they have evolved completely different uses. This provides evidence for divergent evolution or adaptive radiation.
How could two species that evolved on different continents have many similarities?
A common ancestor.
What are the similar body structures in different species tell scientists?
Back down the line, the species came from a common ancestor.
Examples of biochemical evidence of evolution?
Physiological similarities suggest the species evolved from the same ancestor.
Is gradual strutures shred by different species?
IS GRADUAL strutures shared by different species in the evidence of the environment
Can a zebra and a giraffe have offspring?
No. They are different species and haven't had a common ancestor in 54 million years.
