Use use strict;! There's a major error in init.

As for the problem with getTheFirst, since it would be
$array[0]->getDNA()
if you were dealing with an array instead of a reference to an array, then it's
${$array_ref}[0]->getDNA()
when using an array ref. It can also be written as
$array_ref->[0]->getDNA()
So all together, we get
$this->{individual}->[0]->getDNA()</c>
