Standard Mastery: Evidence for Evolution

How does embryology provide evidence for evolution?

• By showing similarities in early development stages among different species, suggesting a common ancestry.

• By demonstrating that species develop in completely different ways with no similarities

• By proving all species were created separately and did not evolve

• Embryology has no relevance to the theory of evolution

Explain how biogeography supports the theory of evolution.

• By showing how species are distributed based on their adaptations to different environments, which supports the concept of natural selection and adaptation driving evolutionary processes.

• By suggesting that species adapt to their environment instantaneously.

• By showing that species never change over time.

• By proving that species are randomly distributed across the globe.

What do fossils reveal about the history of life on Earth?

• Fossils are artifacts left by aliens

• Fossils provide evidence of past organisms, their structures, behaviors, and environments, helping scientists understand evolution, extinction events, and the development of different species over time

• Fossils are created by volcanic eruptions

• 
  Fossils reveal the future of life on Earth

How do homologous structures indicate common ancestry?

• Homologous structures indicate common ancestry by showing differences in structure and function across different species.

• Homologous structures indicate common ancestry by showing similarities in function, despite differences in structure, across different species.

• Homologous structures indicate common ancestry by showing similarities in structure and function across different species.

• Homologous structures indicate common ancestry by showing similarities in structure, despite differences in function, across different species.

Why are vestigial organs considered evidence for evolution?

• 
  Vestigial organs are considered evidence for evolution because they are essential for survival

• Vestigial organs are considered evidence for evolution because they are present in all species.

• Vestigial organs are considered evidence for evolution because they indicate a shared evolutionary history and show how species have changed over time.

• Vestigial organs are considered evidence for evolution because they are the most developed organs.

How does the distribution of species around the world support the idea of evolution?

• The distribution of species around the world showcases how different environments have influenced the evolution of species, leading to the diversity of life we observe today.

• 
  The distribution of species around the world disproves the concept of evolution

• Evolution only occurs within specific regions and not globally

• Species distribution is random and not influenced by environmental factors
