Evolution Biologists define evolution as the change in the frequency of alleles (variations of a gene) in a population. Consider the following situation: Two colors of grasshoppers-brown and red-result from the two variations (alleles) of the color gene in this species. These grasshoppers live in two areas: an area with brown soil, and on an adjacent mountain with reddish soil. ►All the grasshoppers in both areas were accidentally killed by a fire. ► Ecologists re-introduced 1000 red and 1000 brown grasshoppers into each of the two soil areas. And, grasshoppers are a great food source for any bird that can catch them. 1. What do you think the ecologists discovered when they returned to the experimental sites five years later? Babies from the red and browns grasshoppers 2. What factor controls the actual color of a grasshopper? Depends if the color is a dominant allele 3. What determines the color frequency of grasshoppers in the two soil areas? 4. Is there only one direction of change during evolution? Explain yom answer. can evolve in No, because things different ways by different things.
