Evolution and Speciation Quiz

Two kinds of wolf spider rub specialized body parts together in order to produce distinct sounds to attract females. Females of both groups will only allow a male of the same kind to mate with them. It has been found through experimentation, however, that offspring can be produced from crossings between the two groups. What can be hypothesized?

• I only

• II only

• I and II only

• I, II and III

Mammals, birds and reptiles have an embryonic tail that may disappear during development. What is the most likely explanation?

• Mammals have lost their tail by evolution.

• All vertebrates have a common ancestor.

• Mammals, birds and reptiles are identical when they are embryos.

• Some physical similarities of vertebrates are analogous.

Humans have been improving crop species for thousands of years by cross-breeding plants with desirable characteristics. The photograph shows the changes in dry cobs of corn (Zea mays) over 10 000 years. What is the name of the process that was used to produce modern corn?

• Selective breeding

• Adaptive radiation

• Discontinuous variation

• Natural selection

What could be used as evidence for evolution?

• Selective breeding of domesticated animals

• The fossil record

• Homologous structures

• I, II and III

The pentadactyl limbs of mammals, birds, reptiles and amphibians are examples of which kind of structures?

• Homologous

• Analogous

• Vestigial

• Convergent

Which is an example of speciation?

• Selective breeding to produce new varieties of the wheat Triticum aestivum with higher crop yield

• Evolution of different courtship behaviours in separate populations of the cricket Gryllus rubens

• Natural selection leading to an increase in the frequency of darker individuals of Biston betularia

• Selective feeding by koalas (Phascolarctos cinereus) on Eucalyptus species

What process best explains the formation of different pentadactyl limbs?

• Adaptive radiation

• Interbreeding

• Selective breeding

• Convergence

Which pentadactyl limb is adapted for flight?

• A

• B

• C

• D

Which of the following is an example of convergent evolution?

• Bat wings and Bird Wings

• Grasshopper Leg and Crab leg

• Butterfly Wing and Bird Wing

• Seal Flipper and Whale Fin

From the image comparing the similarities between the beta chain of haemoglobin. Which statement is incorrect?

• 146 amino acids were compared in all 5 Species

• The Rhesus monkey shares the most commonality with humans

• Mammals show more similarities to humans than Birds or Fish

• The dog is more similar to the Rhesus monkey than the Bird
