It should be connective tissue.
Physical differences in beaks of birds would develop as a result of different environmental changes.
<h3>What is Evolution?</h3>
This is described as the process in which heritable characteristics are changed in species over successive generations. This occurs as a result of natural selection in which the traits suitable for survival are passed to the offspring.
This is usually as a result of a change in the environmental factors which ensures that the organisms are able to adapt so as not to die out and go extinct in this type of scenario.
