Evolution and Classification Rev & Rei

How has the theory of evolution changed how biologists classify organisms?

• They understood that organism are not similar because they share a common ancestor and an evolutionary history.

• They understood that organism may be similar because they share a common ancestor and an evolutionary history.

• They understood that organism may be different because they share a common ancestor and an evolutionary history.

• They understood that organisma may be similar because they share a common offspring and an evolutionary history.

How is a branching tree organized?

• The common ancestor is at the botom.

• Agrouped by different characteristics they don't share

• Common ancestor at its base, agrouped by characteristics they share.

• Because Darwin said so.

On a branching tree diagram, which characteristics probably developed the earliest?

• The characteristics highest on a branching tree diagram probably developed earliest.

• The characteristics lowest on a branching tree diagram probably developed latest.

• The characteristics are variable

• The characteristics lowest on a branching tree diagram probably developed earliest.

What are two methods scientists use to determine the evolutionary history of a species?

• Structure of branch tree and the chemical makeup of organisms' cells

• Structure of organisms and the chemical makeup of organisms' cells

• They just observe what they appear like.

• Structure of organisms and how organisms put on some makeup
