Monarch butterflies: “Remarkable” instance of concurrent evolution

Spread the love

The famous Monarch butterfly eats milkweed leaves as a caterpillar and drinks its nectar as an adult. High enough levels of milkweed sap can be toxic. How, then, do their predators survive?

To be able to eat this plant, monarchs evolved a set of unusual cellular mutations. New UC Riverside research shows the animals that prey on monarchs also evolved these same mutations.

A Current Biology journal article, published today, describes the research that revealed these mutations in four types of monarch predators — a bird, a mouse, a parasitic wasp, and a worm.

“It’s remarkable that concurrent evolution occurred at the molecular level in all these animals,” said UCR evolutionary biologist and study lead Simon “Niels” Groen. “Plant toxins caused evolutionary changes across at least three levels of the food chain!”

University of California – Riverside, “How to eat a poison butterfly” at ScienceDaily (November 22, 2021) The paper is closed access.

Eric Cassell on the mystery of Monarch butterfly migration. There exists no evolutionary model that satisfactorily explains its origin. That by itself does not prove that gradual evolution didn’t produce such programming, but the lack of such a model should at least give the open-minded pause for reflection.

    yeah, when you believe in a blind unguided process of random mutations, it is really remarkable … in other words, every Darwinist who reads this has to believe in miracles …

    PS: i like all these Darwinian terms – concurrent evolution, parallel evolution, convergent evolution, divergent evolution, reverse evolution – basically, anything can happen, don’t matter whether it fits the theory, English vocabulary is big enough to always rescue Darwinists with some fancy term …

    “Toxins cause evolution” is a flat assertion requiring no explanation. It goes along with the more typical “cosmic rays cause evolution”.

    In reality, toxins and radiation cause death, depriving the organism of a chance to adapt.

    Is this what they really mean? Is this the Dawkins Whistle? Their ACTIONS are all about plain old genocide, not adaptation.
