Exploring Evolution Concepts

What does the theory of evolution by natural selection primarily explain?

• The unchanging nature of species over time

• The immediate transformation of species

• Changes in species over millions of years due to environmental factors

• The creation of new species from nothing

What role do environmental changes play in natural selection?

• They prevent species from evolving

• They determine which traits are favorable for survival

• They ensure all species remain unchanged

• They have no impact on natural selection

What typically initiates the fossilization process?

• Freezing in ice

• Burial under sediment

• Exposure to intense heat

• Being preserved in amber

What are transitional fossils?

• Fossils that link different species by showing intermediate traits

• Fossils showing minimal evolutionary change

• Artificially created fossil replicas

• Fossils that are found in the deepest sediment layers

What does the presence of a common ancestor indicate?

• Species cannot have multiple ancestors

• All animals are directly related to plants

• Different species can share traits due to shared ancestry

• All species come from the same parent species

How does DNA evidence support the theory of evolution?

• By demonstrating similarities in DNA sequences among related species

• By highlighting differences in DNA sequences between species

• By comparing the physical size of organisms

• By showing no similarities between species

• Differences in amino acid sequences indicating evolutionary relationships

• Similarities in metabolic processes

• No relation between any species

What is a common misconception about evolution?

• Evolution claims humans evolved directly from monkeys

• Evolution is just a theory and not supported by evidence

• Evolution is universally accepted without any skepticism

• Evolution involves only large and noticeable changes
