What benefit is there for
turtles to come back to
the same beach they
were born on?
Loggerhead turtles in the Atlantic Ocean return to lay their eggs on
the same beaches where they hatched. Scientists have observed
that the turtles have a “compass sense.” This sense allows them to
use Earth's magnetic field to find their way back to the beaches
where they were hatched.
Which of these terms best describes the turtle's ability to use
Earth's magnetic field?

An Origin of Species
Direction for the assignment:
In your scenario, describe the evolution of a new bird species on your chosen island using the
information provided by the website and the timeline. Your scenarios must be detailed and
describe the environmental pressures faced by the bird species over time. Concentrate on
describing how and when the new species evolved, new physical features, and how the birds
survived and reproduced while being faced with particular environmental challenges. Be sure to
state the name of the ancestral species, the island chosen, and the name of the new species.

Read and Answer the following questions:
1. What brought the pollenpeepers to the island?
2. Were the pollenpeepers “suited” for their new island home?
3. What happened to those pollenpeepers that survived?

Concentrating on:
- Name of the ancestral species
- Island chosen (distance from mainland)
- Name of the new species
- How and when did the new species evolve?
- New physical features
- How the birds survived an reproduced
Final Project:
With your partner, write a similar pair of scenarios describing how a particular species of
pollenpeeper bird evolved from the ancestral species. One scenario will be based on Charles
Darwin’s Theory of Evolution by Natural Selection and the second scenario will be based on
Jean Baptiste Lamarck’s Theory of Acquired Characteristics.
