A multi cellular complex organism evolved to become nigh immortal and with the power to move through time both into the not-so-distant past and future. In this scenario the intelligent of such creature is similar to insect on Earth, they do not perceive the flow of time as our human's brain do.
Let's name this species "Species-ZYX" and the mechanism for leaping across time is unfamiliar to any existing known laws of physics as of this writing but we do know they are discovered somewhere in the Amazon Basin by a group of scientists and explorers.
There are many example of animals which are known to be almost immortal however are there any 21st century scientific methods to test whether Species-ZYX is really capable of time travel?
I'm neither asking for the mechanism behind time traveling bug nor am I interested being lectured by any self proclaimed "physicist(s)" just to debunk the myth of time travel.
