Evidence of Evolution

Front

What is evolution?

Back

Evolution is the process through which species change over time through adaptations and natural selection.

Front

What is a fossil?

Back

A fossil is the preserved remains or traces of an organism that lived in the past, often found in sedimentary rock.

Front

What does the fossil record show?

Back

The fossil record shows the history of life on Earth, illustrating how different species have changed and evolved over time.

Front

What is natural selection?

Back

Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is a common ancestor?

Back

A common ancestor is a species from which two or more different species have evolved.

Front

How do sediment layers relate to evolution?

Back

Sediment layers can show the progression of complexity in fossils, with simpler organisms found in lower layers and more complex organisms in upper layers.

Front

What is adaptation?

Back

Adaptation is a trait that helps an organism survive and reproduce in its environment.

Front

What is the significance of climate change in evolution?

Back

Climate change can create new challenges for species, leading to natural selection and potentially causing extinction if species cannot adapt.

Front

What is the difference between natural selection and evolution?

Back

Natural selection is the mechanism that drives evolution, while evolution is the overall process of change in species over time.

Front

What evidence supports the theory of evolution?

Back

Evidence for evolution includes the fossil record, genetic similarities among species, and observable changes in populations over time.
