Answer:
Evidence for evolution comes from many different areas of biology:
Anatomy. Species may share similar physical features because the feature was present in a common ancestor (homologous structures).
Molecular biology. DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are.
Biogeography. The global distribution of organisms and the unique features of island species reflect evolution and geological change.
Fossils. Fossils document the existence of now-extinct past species that are related to present-day species.
Direct observation. We can directly observe small-scale evolution in organisms with short lifecycles (e.g., pesticide-resistant insects)
2. A cladogram is a diagram that shows evolutionary relationships among groups. It is based on phylogeny, which is the study of evolutionary relationships. ... Each letter on the diagram points to a derived character, or something different (or newer) than what was seen in previous groups.
3. Scientist would use DNA or protein sequences taken from three different organisms to construct a cladogram because , It can be facilitated by cell - surface proteins that recognized DNA. All 3 are parasites or an organism.

5. The birds differ in plumage and body size but the most obvious differences between the birds are the size and shape of their beaks, which are dependent on their food preferences and specialisations. The thinnest beak belongs to the green warbler finch which uses it to probe for insects.
6. camouflage is an adaptation that helps organisms blend in with its surroundings. Blending in helps the animal avoid predators and increases its ability to survive.
Mimicry is an evolved resemblance between an organism and an object which protects them from predators for example how moths evolved to be brown like bark on trees helps them to blend in and reduces their chances of being eaten.
Venom helps animals to immobilise or kill prey or neutralise predators in self defence this benefits the animal because they are less likely to be attacked by predators
7. To be able to reach the food they need. Giraffes feed off of high trees. In order to get that food, they were forced to naturally adapt to the height of the trees.
