Explain the changes in the skeletons during the transition in habitat according to the theory of natural selection

Changes in the skeletons during the transition in habitat according to the theory of natural selection include their modes of histogenesis during the time. There were also observed to have modifications in the exoskeletons which they thought arise exclusively from the neural crest.

According to natural selection, skeletal changes occur gradually as individuals adapt to their environment and pass these changes on to their descendants.

We can arrive at this answer because:

During the transition to a new habitat, some individuals in a group of living beings adapt to the habitat.This adaptation allows individuals who have skeletal modifications to have adaptive advantages and manage to survive in the new habitat.These modifications are passed on to descendants through genetics, which means that new individuals are born with the skeletal modification, while individuals without this modification die before producing descendants.

As a result, the skeletal modification takes place gradually in the population of individuals as new members are born and old members die.
