Bio CW/HW: Tuskless Elephants, Darwinian Evolution?

According to the recent research of Princeton University evolutionary biologist Shane Campbell-Staton and his colleagues, what has caused the 'rapid evolution' of African elephants?

• Climate change

• Ivory poaching

• Habitat destruction

• Introduction of new predators

What is the new feature of evolution that Charles Darwin included in his version?

• Survival of the fittest

• Inheritance of acquired characteristics

• Use and disuse of organs

• Genetic drift

What happens to less suited organisms in an environment according to Darwin's natural selection?

• They adapt immediately to survive

• They migrate to a more suitable environment

• They tend to eventually die out

• They coexist with the fitter organisms

Does the concept of natural selection contradict biblical Creation?

• Yes, it completely contradicts

• No, it is a reasonable idea and does not contradict

• Yes, but only in certain aspects

• The text does not provide information on this

According to the text, what did Peter and Rosemary Grant study for over 35 years?

• The evolution of tuskless elephants

• The behavior of African elephants

• Darwin's theory of natural selection

• Darwin's famous Galapagos finches

What is necessary for beak size and shape to evolve, as found by the Grants?

• A change in the environment

• Genetic variation that provides raw material for natural selection

• The arrival of the fittest

• Spontaneous generation of new genetic information

What can the inherited genetic variety in the species' offspring lead to, according to the text?

• Immediate evolution into a new species

• Potential for variety that already exists in the genes of the parents

• The extinction of the species

• The inability to adapt to environmental changes

What is the main reason tuskless African elephants have begun to dominate, as suggested by the text?

• They have evolved into a new species

• They have developed new genetic information

• The genetic mutations are spontaneously generated

• The existing genetic information is expressed more often

According to the text, what is the key takeaway regarding whether tuskless elephants can still be considered elephants?

• They are no longer considered elephants due to their lack of tusks

• They have evolved into a different species

• They are still elephants and have not evolved into something else

• They are a new kind of species that evolved due to Darwinian change
