12/8/23 Warm Up (Evidence of Evolution & Cladograms)

Front

What evidence do fossils provide for evolution?

Back

Fossils show how life forms present today are different than those from the past.

Front

What do similarities in bone arrangements suggest about organisms?

Back

These organisms share a common ancestor.

Front

On a cladogram, how can you identify the closest relative of an organism?

Back

The closest relative is the organism that shares the most recent common ancestor.

Front

What does a greater number of differences in DNA base pairs indicate about two organisms?

Back

The more differences in the DNA base pairs, the more distantly related they are.

Front

What type of structure is a bat wing compared to a butterfly wing?

Back

Analogous structure.

Front

What is a homologous structure?

Back

Structures that are similar in different species due to shared ancestry.

Front

What is an analogous structure?

Back

Structures that serve similar functions but are not derived from a common ancestor.

Front

What is a vestigial structure?

Back

A structure that has lost most or all of its original function through evolution.

Front

How do sedimentary rock layers provide evidence for evolution?

Back

Different layers show how the environment has changed over time and the types of organisms that existed.

Front

What is a cladogram?

Back

A diagram that shows the evolutionary relationships among various biological species.
