Evidence of Evolution

Front

Body structures with similar parts but different functions are called: vestigial structures, homologous structures, adaptive structures, analogous structures

Back

homologous structures

Front

The study of embryos of various organisms to show a common ancestor is called:

Back

embryology

Front

Two organisms that are closely related would have:
- similar DNA sequences
- exactly the same DNA sequences
- no proteins in common
- completely different DNA sequences

Back

similar DNA sequences

Front

What does Darwin's theory of evolution suggest?

Back

species change over time

Front

Lizards, birds, humans and whales share: vestigial structures, analogous structures, homologous structures, fossil structures

Back

homologous structures

Front

Which of the following is NOT evidence for evolution?

• Many animals have homologous structures
• Many animals have vestigial structures from an ancestor
• We can observe changes in life forms by observing the fossil record
• Many organisms share the same colour

Back

Many organisms share the same colour

Front

How do fossils provide evidence that evolution has happened on Earth?

Back

Fossils show how life forms present today can resemble those from the past

Front

Scientists compare organisms' DNA to support the theory that all species share a common _________________.

What can be determined from this diagram?
Options: The organisms share a common ancestry., The organisms belong to the same species, The organisms are native to the same geographic areas., The organisms will grow into anatomically similar adults.

Back

The organisms share a common ancestry.
