Natural selection

Contrary to media hype, anole lizards on the Bahamas are not evolving

Natural selection can only select for the attributes an organism needs to survive, so how is it that creatures are endowed with a whole lot more than necessary?

Flightlessness is devolution, not evolution.

White squirrels appear in a handful of towns in North America. How did they get there? Is it evolution? Is white fur a beneficial mutation or a curse?

Killifish have been found living in polluted rivers with levels of industrial toxins 8,000 times the lethal dose.

Not only can species change over time, but they can merge and split as well. This can be described with the ‘braided baramin’ concept.

Where do species come from? How much change is allowed? If species change, what separates creation from evolution?

When fire ants threaten lizard populations, it really is ‘survival of the fittest’. But ‘evolution’? No!

The capacity for dark colouring is now known to be in each moth; and its caterpillar can detect twig colour through its skin, changing its colour to match.

A colour mutation that camouflages deer mice against a sandy background is a great example of natural selection.

Much to trophy-hunters’ disappointment, bighorn sheep on Ram Mountain are not what they were. But is it evolution?

If you’re a fisherman who reckons that fish are now smaller, and there are fewer of them around, you’re very likely right.

Why the elephant is losing its tusks (and it’s not evolution!)

Is the Tibetan snow lotus evolving to elude detection?
