What is natural selection?

Back

Natural selection is the process by which species adapt to their environment, leading to the survival of individuals with favorable traits.

Front

What role does natural selection play in species survival?

Back

Natural selection determines the survival of a species in a changing environment.

Front

What is artificial selection?

Back

Artificial selection is the process by which humans breed plants and animals for specific traits.

Front

How has biotechnology changed artificial selection?

Back

Biotechnology has introduced genetic engineering, allowing for more precise manipulation of traits in organisms.

Front

What can the fossil record tell us?

Back

The fossil record documents the existence, diversity, extinction, and change in life forms throughout Earth’s history.

Front

What is the significance of anatomical structures in evolution?

Back

Anatomical structures provide evidence of common ancestry and help to identify similarities and differences between extinct and extant organisms.

Front

How do geological processes affect species survival?

Back

Geological processes can lead to changes in the environment that affect population dynamics and extinction events.

Front

What is the structure of the Earth?

Back

The Earth is composed of layers including the crust, mantle, outer core, and inner core.

Front

What is plate tectonics?

Back

Plate tectonics is the theory that explains the movement of the Earth's plates and the associated geological phenomena.

Front

What is the rock cycle?

Back

The rock cycle describes the processes that create and change rocks, including igneous, sedimentary, and metamorphic rocks.
