<span>These
islands have different ecologies and most are not connected to each other by landmass.
Therefore, the organism adapt to each of the different ecologies on their

to each other and would not breed randomly. They therefore formed different species
by allopatric speciation.</span>
The correct option from given options is "b", that is <span> it changed ideas about which animals were closely related.
</span>Cladistics<span> was </span>invented for the purpose of improving on taxonomy and it is a way to deal with biological classification. DNA technology lead to more use of cladistics because it changed ideas about which animals were closely related and also it showed new evolutionary relationships between animals.
