Evolution and Speciation Quiz

What is the main focus of the video tutorial?

• Photosynthesis in plants

• Speciation and natural selection

• Cell division

• Human anatomy

What mistake do students often make when analyzing the evolutionary progression of whales?

• Ignoring the images

• Focusing only on the text

• Not reading the questions

• Relying solely on visual cues

What is the significance of the non-functioning pelvis in modern whales?

• It shows they have evolved from land animals

• It is used for swimming

• It is a vestigial structure

• It indicates they can walk on land

What does the term 'modification with descent' refer to in the context of evolution?

• The gradual change in species over time

• The immediate change in species

• The extinction of species

• The process of photosynthesis

Which ancestor of whales is believed to have lived both on land and in water?

• Pachycetus

• Durodon

• Ambulocetus

• Blue whale

What is a key feature of the Durodon in the evolutionary progression of whales?

• It is the smallest species

• It has large flippers and small hind limbs

• It can fly

• It has a long neck

Why is the Ambulocetus considered a transitional species?

• It has no limbs

• It has characteristics of both its ancestors and modern whales

• It is the largest species

• It is the most recent species

According to Lamarck, why do modern whales lack legs?

• They never had legs

• They evolved from fish

• They lost their legs due to a genetic mutation

• Their ancestors used their legs less over time

How does Lamarck's theory explain the evolution of traits?

• Through natural selection

• Through genetic drift

• Through acquired characteristics

• Through random mutations

What is the role of acquired characteristics in Lamarck's theory?

• They are passed to offspring

• They are only found in plants

• They are not passed to offspring

• They are irrelevant to evolution
