    This is an article about possible devolution of a species.

    “This case is exceptional because the genes for producing full-size adult males should have deteriorated over time because they weren’t used by the dwarf males,” Vrijenhoek said. “But apparently the genes are still there.

    “It’s a throwback to an earlier ancestral species more than 40 million years ago,” he said. “We’re continuing to collect more species to see what their genes are telling us.”

    How can it be evolution if the genes are still available?

    Is this true of other species.

    I do not think the genes are there but I can conceive of them being developed under the right conditions. I remember hearing of a species that would change to look like another species if the temperature went low enough.
