Macro and Micro Evolution

What was the main problem with Lamarck's evolutionary theory?

• Individuals acquired traits from the evolutionary process, which in turn, was passed on to offspring.

• Populations that failed to adapt to new environments still evolved.

• Some groups within a species never passed their traits on to the next generation.

• Individual species adapted to their environment, they then passed those adaptations to offspring.

The generation to generation change in a gene pool is referred to as...

• Linear evolution

• Macro-evolution

• Micro-evolution

• Branching evolution

The main difference between Micro-evolution and Macro-evolution is...

• Micro-evolution is directly observed and Macro-evolution is not.

• Macro-evolution creates new species, Micro-evolution does not (directly).

• Both of these statements are correct

• Both of these statements are incorrect

The end result of macro-evolution is believed to be...

• extinction

• speciation

• adaptation

• nothing - no change.

_________ is the process of change by which species of organism change over time.

• Nucleotides

• Evolution

• Mutation

• Carbon

If scientists find fossils of a type of mosquito on the bottom layer and find fossils of beetles towards the top layer, what can scientists infer?

• Mosquitos ate the beetles

• Mosquitos are older fossils than beetles

• Beetles are older fossils than mosquitos

• Both mosquitos and Beetles must have lived at the same time.

All the individuals of a species that live in a particular area are called a 

• group
• population
• variation
• fossil

When an organism completely dies out, it is called.....

• Adaption
• Extinction
• Fossilization
• Mutation

Mistakes or changes that occur int he DNA sequence are called....

• adatations
• Darwinism
• mutations
• natural selection

Whales, which live in the water, have hips. These structures are important for carrying the weight of animals that walk on land. Finding this body part in animals that don’t walk on land is best explained how?

• Whales have evolved this structure because it might be useful in the future.

• Whales are able to interbreed with other animals that have hips.

• Whales have a diet that includes other animals that have this structure.

• Whales share a common ancestor with animals that walk on land.
