Organisms such as dolphins and sharks are distantly related but show body types that are very similar as a result of living in similar environments. This is an example of

The emergence of major groups, or clades, such as the dinosaurs, mammals, or flowering plants, is known as

There are over __________ different species of organisms documented. And there are estimated to be between _______________ currently living.

The scientific name for Sea Otter is

Polyploidy, a condition where cell division results in cells with abnormal numbers of chromosomes, may lead to the formation of new species. This is a result of

The habitable zone is defined as

The quote “I have called this principle, by which each slight variation, if useful, is preserved, by the term Natural Selection.” is attributed to

Rock samples may have their age determined in potentially two ways. The method that examines whether the rock is found above or below another rock is called _____.

How would you date a sample of rock that you suspect as being one of the earliest on Earth?

In explaining how organisms in nature could evolve over time, Charles Darwin examined how organims under human control such as “fancy pigeons” could also change. He called this change that was human directed

In most situations the sedimentary rock layers CLOSEST to the surface

Trilobites are a group of arthropods that existed only during the Paleozoic era. If you were to find a rock sample that contained trilobite fossils you could use this to gauge the age of the rock. This would be an example of using trilobites as:

The length of time required for half of the radioactive atoms in a sample to decay to product is its

In the biology classroom we have an African Starfish flower. When the flowers bloom they have the scent described as “rotting meat”, which attracts flies. The flies then are covered with pollen which is carried to other flowers. This is an example of
