Lizard Adaptation and Places in the Environment

Researchers studying South American tree iguanas were a mite stumped because they were not doing what they are supposed to do. Namely, adapt and evolve. Instead, males and females of some species were taking ecological niches that could have been filled by variations. A recent study of these iguanas does not support universal common ancestor evolution.

The Master Engineer designed critters and other organisms to adapt and fill various niches. This is part of how they were designed to keep from going extinct, especially after the changes on Earth after the Genesis Flood. Darwin's disciples falsely call these variations "evolution", but nothing is changing into something completely different.
In a recent study of South American lizards of the Liolaemus genus (commonly called tree iguanas), native to Chile and Argentina, researchers discovered that interspecies sexual size dimorphism (hereafter called SSD according to the journal article) may be limiting speciation. The ecological niches, which can normally be filled by different species, may in fact be exploited by different sexes of the same species.

According to the prevailing theory, if SSD is driven by ecological opportunity alone, there should be no clear-cut trend for size dimorphism among males or females. Alternatively, if SSD is driven primarily by sexual selection, the expectation is that females would be consistently larger than males or vice versa.
