Conservative Living Fossil: No Change in Swim Stroke for “270 Million Years”

When evolutionists want to convince others that their worldview is credible, they often define evolution as change over time. Their definition is misleading, as they really mean that all living beings are the descendents of the first living unicellular creature.

Still, the fossil record shows that animals tend to be very conservative. They are reluctant to change their habits.

A recent article in New Scientist says: “Amphibians have been using the same swimming technique for 270 million years, a set of ancient footprints reveals.”

The article discussed the discovery of ancient fossilised tracks in the Italian Alps. Assumed to be “between 270 and 283 million years old,” the tracks are practically identical to what modern salamanders would make.

Massimo Bernardi at the Science Museum in Trento, Italy, who found the tracks with his colleagues, says that the tracks “are the first fossil record of an animal that old switching from walkingto swimming.”

Salamanders are living fossils. When it comes to swimming and walking, they have had a tendency to stick to good old habits.
