Evidences:


1.Grazing the islands of Hawaii is a family birds commonly called the Hawaiian honeycreepers.All hawaiian honeycreepers have similarities in sketal and muscle structure that indicate they are closely related. However, each of the hawaiian honeycreeper species has a bill specialized for eating certain foods.Scientists suggest that all 25 honeycreeper species apparently arose from a single species that migrated to Hawaii.

2. Death Valley submerged in water and it dilluted into ponds. And now each pond has diffrent fish in each place.

3. plants in diffrent places have common ancestors.

4.The absence of some species from environments that would suit them, and closer relationships between species that are geographically near each other than between species that inhabit similar environments.

5. Once a species reaches an island and establishes a value population,it may undergo evolutionary change because of genetic drift,climatic differences between the mainland and the island of the absence of preditors and morphology of island species of ten evolve rapidly unlike any related species elsewhere. Examples, include the giant land tortoises of the Galapagos,and the Komado dragon,a species of monitor lizard from Indonesia.

Molecular Biologist

Evidences:


1.The University of Cytochrome C is evidence that all aerboic organisms probably descended form a common ancestor that used this compound for respiration.

2. Further Studies of cytoplasm C in different species reveals variations in the amino acid sequence of this molecule. For example, the cytochrome C of monkeys and cans is more similar than the cytochrome C of monkeys and fish'

3.Their students reveal evidence of degrees of relatedness between different species. This evidence implies that some species share a more recent common ancestor than other species do.

4. From such evidence scientists have inferred that the evolutionary relationships between different species of organisms

5. Certain blood proteins found in almost all organisms give additional evidence that these organisms descended form a common ancestor. Such biochemical compounds, including cytochrome c and blood proteins, are so complex it is unlikely that almost identical compounds would have evolved independently in widely different organisms. Further studies of cytochrome c in different species reveal variations in the amino acid sequence of this molecule.

6.For example, the cytochrome c of monkeys and cows is more similar than the cytochrome c of monkeys and fish. Such similarities and differences suggest that monkeys and cows ate more closely related than are monkeys and fish. Scientists have similarly compared the biochemistry of universal blood proteins.

Paleontologist

Evidences:


1.You can sometimes tell the type of fossil based on punctures in them.

2.You can determine the amount of blood vessels by the sizes and shapes of the spaces.

3. Records show that over time,the amount of feathers a velociraptor had increased through the years. The significance was how many feathers were added over time.

4. Fossil slothes used to be different in shape and size. Today they are medium and almost monkey like. The significance is the adaptation that were used.

5. Whales used to have feet but over time they evolved into fish like things.

Anatomist

Evidences:


1. Snakes have tiny pelvic bones and limb bones,and some cave-dwelling salamanders have eyes even though members of the species are completely blind. Function less parts are called vestigal organs.

2. A butterflies wing is smaller and a birds wing is larger and wider.

3. A whale uses their fin to move among the water. And a humans main purpose for their hand is to grab things.
