Evolution #2

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

A process by which unrelated organisms evolve similar characteristics

• Shared derived Characteristic

• Convergent evolution

• Divergent evolution

• Brenching Tree diagram

Charles Darwin called the ability of an organism to survive and reproduce in its specific environment

• diversity

• fitness

• adaptation

• evolution

Each node on a cladogram represents

• the last point at which two groups shared a common ancestor.

• the point at which one or more species became extinct.

• the most recent point at which a trait was lost in a certain clade.

• the point at which two clades joined and became monophyletic.
