Solution
The correct combination of statements is I, II, and III.
Statement I is correct as it mentions that recent studies support competition as suggested in ‘Gause’s Competitive Exclusion Principle’.
Statement II is also correct as it accurately describes Gause's hypothesis, which states that if two species compete for the same resources, one will be eliminated by the other species.
Statement III is correct as it points out that more recent studies suggest that species facing competition might evolve mechanisms that promote co-existence rather than exclusion, which is a modern understanding of species interaction and evolution.
Statements IV and V are incorrect. Gause's competitive exclusion principle is not effective when resources are in excess, it is effective when resources are limited. Unlimited resources do not necessarily give better opportunity for adaptation, as adaptation is driven by selective pressures, which often come from limited resources.
