On the bottom half of the timeline, have students label the 31 events from the "Rise of Evolution" segment.

What two conditions must be true for a group of animals to be considered the same species? They can reproduce and have fertile offspring. Lamarck’s ideas of evolution are known as inheritance of acquired characteristics. What was incorrect about his theory of how organisms evolve? The theory is incorrect because acquired characteristics do not get […]

Biology is subdivided into separate branches for convenience of study, though all the subdivisions are interrelated by basic principles. Thus, while it is custom to separate the study of plants from that of animals (), and the study of the structure of organisms from that of function (), all living things share in common certain biological phenomena—for example, various means of reproduction.
