Pangea German meteorologist Alfred Wegener thought that the
continents were all joined together at some point in time in the
past. He called this large supercontinent Pangea (Pangaea).
Wegener proposed, in 1912, the hypothesis of continental
drift. According to his hypothesis, continents have slowly
moved over many years to their current location. Wegener's
hypothesis of continental drift was highly controversial
The idea was controversial because the evidence
Wegener presented to support his hypothesis didn't
convince many people.
A. Describe Wegener's theory of continental drift using
the evidence he gathered to support his theory.
B. Explain why the fossil of an ocean fish found on two
different continents would not be good evidence of continental
drift.

(me out over the last several centuries, scientists have made the following broad observations while investigating several branches of the life sciences: -the fossil record shows that different types of organisms have existed at different times in earth's history. -many organisms have similar body structures that seem to be adapted to different ways of living in their environment. -organisms of different species often share similarities in stages of embryonic development. -many species share genetic similarities, and almost all organisms use the same basic building blocks to construct proteins. -often, the extent of two species' similarities can be predicted from their geographic closeness to each other. -a great deal of change has been observed among species that have experienced strong selective pressures through many generations. scientists have carefully considered and rigorously tested the observations listed above. when scientists offer a of these observations, they are making 1.) testable explanation, deductive explanation 2.) scientific interference, scientific law
