Looks Questionable to Me....

Not all journal articles are created equal.  Keep an eye out for red flags when reading articles during a literature review.

For example....

ex·tinc·tion
ikˈstiNG(k)SHən/
noun

1. the state of a species, family, or larger group having no living members.
   

Last time I checked, lions weren't extinct....  Not even Panthera leo goojratensis (aka Panthera leo persica, the Asiatic lion) for which this article is about.
