Which of the following did NOT occur while Darwin was on his trip aboard the HMS Beagle?
He presented his theory of natural selection
He mapped the coast of South America.
He began to develop ideas that were similar to Alfred Wallace’s
He noted that the beaks of the finches on each of the Galapagos Islands reflected what they ate.
What is believed to have caused the organism seen below to go extinct?
Formation of Pangaea
Cavemen breath

The front fin of a whale has bones that are similar to a human arm. This is an example of _______.
Vestigial Structure
Allopatric Trait
Sympatric Trait
Homologous Structure
There are two types of pond turtles that live behind Mr. Eisler’s house: pond turtles that have a hard shell and pond turtles that have a soft shell. Both types of turtles eat the plants that grow on the bottom of the pond. Some die of starvation every year because there are a limited amount of plants at the bottom of the pond. Mr. Eisler has also seen otters using their sharp teeth to eat the turtles. He noticed that they tend to prey more on the soft shell ones because they are easier to break through and chew. Both types of turtles lay 80-120 eggs at a time. Most of them will hatch, however very few will reach maturity due to the starvation and predation.
Which turtle will natural selection select for?
Soft ShellTurtles
Hard Shell Turtles
