Exploring Evolution and Natural Selection Concepts

What does comparative anatomy suggest about species with similar body structures?

• They may have descended from a common ancestor.

• They have the same diet.

• They have identical genetic makeup.

• They share the same habitat.

What is the main difference between homologous and analogous structures?

• Analogous structures are always found in mammals.

• Homologous structures are not similar in appearance.

• Analogous structures do not share a common ancestor.

• Homologous structures perform different functions.

Which of the following is an example of a homologous structure?

• The tails of a monkey and a fish.

• The wings of a butterfly and a bird.

• The fins of sharks and the flippers of dolphins.

• The arm of a human and the wing of a bird.

How do analogous structures arise?

• Through direct genetic inheritance from a common ancestor.

• By species living in the same habitat.

• Through similar evolutionary pressures, without a common ancestor.

• By consuming similar types of food.

Why are fossil records crucial for understanding evolution?

• They reveal the color of ancient species.

• They indicate the diet of extinct species.

• They show how species have changed over time.

• They provide DNA evidence of ancient species.

What role do fossils play in understanding the history of life on Earth?

• They are used to predict future evolutionary trends.

• They are primarily used for carbon dating.

• They help in mapping ancient geological structures.

• They provide insights into the evolutionary changes of species.

What evolutionary trait has the brown mouse in New York City developed?

How have bed bugs adapted in recent decades?

• They have become smaller in size.

• They have developed wings.

• They have become resistant to eradication efforts.

• They have started to feed on plastic.

What does the development of a perch in a flower demonstrate?

• The impact of pollution on plant growth.

• Plants developing mobility.

• Evolutionary adaptation for better pollination.

• Animal training by plants.

What unique behavior have Moscow's stray dogs exhibited?

• They use zebra crossings to cross streets.

• They have learned to speak Russian.
