Evolution

Which of the following is a fossil?

• a plant that has recently died
• a group of organisms that can reproduce
• a structure or organ that no longer functions
• a trace of an organisms that existed in the past

In natural selection, the selective agent is the

• humans
• mutations
• breeders
• environment

what did Charles Darwin observe in finch populations of the Galapagos Islands off the coast of South America?

• different species on different islands
• all species on one of the islands
• identical species on all the islands
• the same species as North America

What is the process in which humans breed organisms for certain traits?

• natural selection
• inheritance
• artificial selection
• descent withOUT modification

The Physical remains of a plant or animal preserved in rock or Earth's crust. 

• Adapt
• Fossil

Some organisms that share a common ancestor have features that have different functions, but similar structures.  These are known as

• vestigial structures
• analogous structures
• homologous structures
• fossil structures

Who is the father of evolution?

• Darwin
• Mendel
• Newton
• Einstein

What is the study of organisms at the early stages of development?

• DNA studies
• embryology 
• extinction
• fossil record

The fossil record provides evidence that 

• Fossils cannot be dated.
• All species were formed during Earth’s formation and have changed little since then.
• The fossilized species have no connection to today’s species.
• Older species gave rise to more-recent species.

Which of the following is an example of a vestigial structure?

• the wings of a red-tailed hawk
• the hind limbs of a house cat
• the fins of sharks
• the tailbone of a human
