Question
Transcribed Image Text:(b) There is a positive correlation between branch width of trees and hind limb length of the brown
anole lizard:
Wide branch diameter = long hind limbs
Narrow branch diameter= short hind limbs
A group of lizards becomes separated from the main group on Island A due to a catastrophic
hurricane that carries this small group out to sea. A few lizards are able to make it to uninhabited,
dry land (Island B) and breed over several generations separated from the lizards on Island A.
Scientists, monitoring the lizard populations, record the change in hind limb length of these two new
populations over time. The results are shown below:
Island A
Island B

Linear (Island B)
