The process in which a species has changed over time is known as this.
What is evolution?
100
This French Naturalist postulated that selective use and disuse of organs by organisms resulted in traits being gained or lost in their lifetime, and these traits were then passed on to their offspring.
Who is Lamarck?

The ability of an individual to survive and reproduce is known as this.
What is fitness?
100
The principle that all species can be traced back to a common ancestor is known as this.
What is common descent?
100
A line of evolutionary evidence that uses the study of developing individuals is known as this.
What is embryology?
200
A well supported testable explanation of phenomena that have occurred in the natural world is known as this.
What is a theory?
200
This English economist reasoned that sooner or later the human population would consume all available living space and resources.
Who is Malthus?

Any inherited trait that increases an organism's chance of survival is known as this.

What is an adaptation?

200

Finding fossils in different rock layers in the same place allows us to do this

Preserved remains of ancient organisms used by Darwin to form his theory are known as this.
What are fossils?
300

This term refers to the availability of different traits and alleles within a population. The variety within the species.

What is variation?

300

The concept that organisms who are the best suited to their environment will be the most successful

What is survival of the fittest?

300

Unrelated species with similar adaptations but in different parts of the world are similar due to this type of evolution.

What is convergent evolution?

Similarities between the bone structures of paws, hooves, wings, and fins are examples of this.
What are homologous structures?

The concept of humans selecting desired traits in species for exploitation is known as this.
What is artificial selection?
400
The process in which nature determines which individuals/adaptations survive is known as this.

What is the struggle for survival or competition?

500

The concept that over time, offspring will look similar to their parents, but with some minor changes.

500

Type of macroevolution that leads to the formation of new species
