Evidence of Evolution

Front

What is evolution?

Back

Evolution is the process by which different kinds of living organisms develop and change over time through natural selection.

Front

What is a cladogram?

Back

A cladogram is a diagram that shows the evolutionary relationships among various biological species based on similarities and differences in their physical or genetic characteristics.

Front

What are homologous structures?

Back

Homologous structures are body parts in different species that are similar because they share a common ancestor, even if they have different functions.

Front

What are vestigial structures?

Back

Vestigial structures are body parts that have lost their original function through evolution, like the human appendix.

Front

What is embryology?

Back

Embryology is the study of embryos and their development, which can show similarities between different species.

Front

What is natural selection?

Back

Natural selection is the process where 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

What is the fossil record?

Back

The fossil record is the history of life on Earth as documented by fossils, which provide evidence of past organisms.

Front

What is biochemistry?

Back

Biochemistry is the study of the chemical processes and substances that occur within living organisms, which can show evolutionary relationships.

Front

What is the significance of jaws in evolution?

Back

Jaws are a significant evolutionary adaptation that allowed vertebrates to become more efficient predators.
