Evidence of Evolution

Front

What is evidence of evolution?

Back

Evidence of evolution refers to the various types of data and observations that support the theory that species change over time through processes like natural selection and adaptation.

What do fossils in upper layers of sediment indicate?

Back

Fossils in upper layers of sediment are typically more complex and represent more recent life forms, while fossils in lower layers are simpler and represent earlier life forms.

Front

What is the fossil record?

Back

The fossil record is a historical sequence of life on Earth, preserved in sedimentary rock, that provides evidence of the evolution of species over time.

Front

What happens to species that cannot adapt to environmental changes?

Back

Species that cannot adapt to environmental changes may face extinction, as they are unable to survive in their changing habitats.

Front

What is a common ancestor?

Back

A common ancestor is an early species from which two or more different species have evolved, indicating a shared evolutionary history.

Front

How do scientists use fossils to understand evolution?

Back

Scientists study fossils to understand the physical characteristics of ancient organisms and how they relate to modern species, providing insights into evolutionary changes.

Front

What role does climate change play in evolution?

Back

Climate change can create new challenges for species, leading to adaptations or extinction, thus influencing the course of evolution.

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, leading to evolutionary changes.

Front

What evidence suggests that dinosaurs went extinct?

Back

Evidence such as fossil records and geological data suggests that dinosaurs went extinct due to catastrophic events like asteroid strikes or volcanic eruptions that altered the climate.

Front

What is adaptation in the context of evolution?

Back

Adaptation refers to the process by which a species becomes better suited to its environment through changes in traits over generations.
