What is the common ancestor of birds and bats?

The common ancestor of birds and bats must have had wings and flown. Humans live in habitats very different from the habitats of both birds and bats. Humans and bats share a closer evolutionary history with each other than with birds.

Is the skeletal structure of bats similar to that of humans?

While only birds and bats have wings, the underlying skeletal structure is more similar in bats and humans. What is the most reasonable conclusion one can draw from a comparison of these structures?

What is the difference between the first and the second skull?

The second skull was that of a species that could walk upright, and the first one was not. Both skulls belonged to the “the toolmaker” species that the Leakeys had been searching for.

Which animal has a smaller brain and larger eyes?

The cow Bos primigenius (which is bred for meat and milk) has a smaller brain and larger eyes than closely related wild species of ungulates. These traits most likely arose by _____.

What conclusion can be drawn from a comparison of birds and bats?

What is the most reasonable conclusion that can be drawn from a comparison of these structures? The common ancestor of birds and bats must have had wings and flown. Humans live in habitats very different from the habitats of both birds and bats. Humans and bats share a closer evolutionary history with each other than with birds.

Which animals are more closely related than sharks and birds?

Mammals and turtles are more closely related than are lungfishes and sharks. Descendants of organism (d) have legs. Birds and ray-finned fishes have a notochord and jaws.

Which of the following animals have a vertebral column?

Rays and frogs have a vertebral column. Lancelets and coelacanths are more closely related than are chimaeras and coelacanths. Organism (a) is a common ancestor of all chordates.

Which pair of species is more likely to be closely related?

Which pair of species is more likely to be closely related: A and B or B and C? Explain. Species B and C are more likely to be closely related.

Are lungfish related to coelacanths?

Both coelacanths and lungfishes share the category sarcopterygian with the tetrapods, which includes land animals like reptiles, amphibians, birds, and mammals, e.g. humans. Evidence suggests that the tetrapods are related more closely to lungfish than to coelacanths. The Queensland lungfish, Neoceratodus forsteri, is endemic to Australia.

Which is more closely related to chimaeras and coelacanths than to lampreys?

Lancelets and coelacanths are more closely related than are chimaeras and coelacanths. Organism (a) is a common ancestor of all chordates. Hagfishes, lungfishes, and frogs have lobed fins. Organism (c) is a common ancestor of lampreys and lungfishes.

Are animals B and C more closely related to each other?

Although B and C have the same number of differences, they may still be very different from one another, as the data doesn’t show where the differences are. A student who looked at these results concluded that animals B and C are more closely related to each other than to any of the other animals.

Which is the best evidence that two birds belong to the same?

(5.2) Which of the following is the best evidence that two birds belong to the same species? The two birds eat the same food. The two birds have common behaviors. The two birds are the same size and color. The two birds mate and produce fertile offspring. (5.2) The table shows taxonomic information for the gray wolf and four other species.

Do birds and bats have a common ancestor?

While birds and bats do have a common ancestor, wings evolved separately in the two species. The fact that birds and bats have the same bones in their wings shows that they must be closely related.

What is the common ancestor of birds and crocodiles?

C. Crocodiles, bats, whales, and birds evolved from a common ancestor. D. The common ancestor of birds and crocodiles was a whale. Crocodiles, bats, whales, and birds evolved from a common ancestor. Select ALL the correct answers. The diagram below shows the similar limb structures of a dolphin, a horse, and a bat.

Are crocodiles and birds homologous?

Birds and crocodiles both provide parental care to their offspring; this behavior was inherited from a common ancestor and is homologous. Do crocodiles have homologous structures?

What are the bones in a bat’s body called?

This small bone, which helps support the uropatagium (which is that flap of skin that extends between the back legs and the tail) is called the calcar, or calcaneum. Bats also have an extra bone at the elbow. This very small bone, which is the upper arm equivalent of the patella, is called the ulna sesamoid.

What is the skeleton of a bat like?

The skeleton of a generalised bat is shown below. The most obvious changes are of course in the greatly elongated bones of the fore limbs, particualrly the metacarpals and phalanges. Looking a little closer, we will find that some bats have developed an extra bone on the hind limbs near the ankle.

How many animals have the same skeletal structure?

Shown below are images of the skeletal structure of the front limbs of 6 animals: human, crocodile, whale, cat, bird, and bat. Each animal has a similar set of bones.
