Quiz 12: Evolution

Which of the following is NOT considered a type of homology?

• Embryology

• Vestigial structures

• Sequence/ Molecular homology

• Photosynthesis

What does the term "biogeography" refer to?

• The study of fossil records

• The geographic distribution of species

• The analysis of DNA sequences

• The comparison of embryonic development

Which of the following is an example of an analogous structure?

• Forelimbs of humans and cats

• Wings of birds and bats

• Torpedo shape of sharks and dolphins

• Tails of mice and rats

What is the primary characteristic of a vestigial structure?

• It has a crucial function in the organism

• It is only found in extinct species

• It has little or no use but is an evolutionary remnant

• It is always present in embryos but disappears in adults

Which of the following is an example of direct observation of evolution?

• Fossil records of dinosaurs

• DNA sequence similarities between species

• Insect populations becoming resistant to pesticides

• The presence of pharyngeal pouches in vertebrate embryos

What does embryology provide evidence for in the context of evolution?

• The age of fossils

• The geographic distribution of species

• Similarities in early development among different organisms

• The function of vestigial structures

How does molecular homology support evolutionary relationships?

• By comparing the shape of different organisms

• By analyzing similarities in DNA and amino acid sequences

• By studying the fossil record

• By observing the behavior of living organisms

What is a key characteristic of endemic species?

• They are found worldwide

• They are always endangered

• They are found only in a specific geographic location

• They are always the dominant species in their ecosystem

How does continental drift relate to biogeography?

• It explains why all continents have the same species

• It shows how species evolve in isolation

• It explains similarities between species on different continents

• It proves that all species originated from a single location
