The dichotomous key used to identify the antelopes might be based on the presence/absence of certain muscles, weight, etc.
<h3>What is a dichotomous key?</h3>
A dichotomous key is a system to classify species and/or taxonomic groups by using two different choices.
For example, the presence/absence of certain physical features can be used to identify the antelopes.
Moreover, the threshold in certain features such as weight/height can also be used to classify species.
