Based on the information shown in the data table and the cladogram shown below, which of the following best describes the evolutionary history of birds? Claws/Nails Feathers Jaws Lungs Mammary glands
Bird X X X X
Hagfish
Lizard X X X
Rabbit X X X X
Salamander X X
Tiger X X X X
Trout X

Image depicts a cladogram with hagfish, trout, salamander, lizard, bird, rabbit, and tiger represented. Trout diverge from hagfish with the introduction of jaws. Salamander diverges from trout with the introduction of lungs. Lizard diverges from salamander with the introduction of claws and nails. Bird diverges from lizard with the introduction of feathers. Rabbit and tiger diverge from lizard with the introduction of mammary glands.
They are more closely related to salamanders than they are to lizards.
They evolved into a separate species as a result of having claws and feathers.
They have jaws, lungs, and feathers, but lack claws, nails, and mammary glands.
They share a more recent common evolutionary ancestor with lizards than they do with salamanders.

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.
