Question

in the 1930s the cane toad was introduced into eastern Australia to help control a destructivebeetle population. The population of cane toads quickly increased and spread westward.Today.the king told population continues to move westward at greater rates than in the past periodscientists compared the traits of cane toads that have recently invaded a region of WesternAustralia with cane toads that have inhabited a region of eastern Australia since the 1940s. Thescientists determined that cane toads from populations that are currently expanding intowestward Australia have different characteristics than those of cane toads from establishedpopulations in eastern Australia. Specifically the western Australian cane toad now have thefollowing characteristics.larger forearms, a narrower pelvis, longer hind legs the offspring of the western toads alsohave the traits of their parents how does this example support the scientific theory ofevolution?a. By showing that different inherited adaptations can be observed in separate populationsof a species.b. by showing that multiple alleles can form in populations of a species existing in differentlocations.c. by showing that competition for mates can lead to changes in characteristics within aspeciesd. by showing that specific mutations can prevent the original species from migrating.

Answer 1

This example supports the scientific theory of evolution by showing thar multiple alleles can form in populations of a species existing in different locations. (option b)
