Fish with Lungs
The idea of fish with lungs sounds about as strange as elephants with wings. The difference is there really are fish with lungs.
In fact, there are many varieties of lungfish found in Australia, Africa, and South America. In Australia, they live in quiet pools of water that become stagnant in the summer. Because there isn't much oxygen dissolved in the water, these fish need lungs in order to breathe air just as we do. Lungfish in the South American swamps spend their time resting in burrows when the swamps dry up in the summer. In a similar way, the lungfish in Africa spends the dry season burrowed in the mud with a breathing tube to the surface.
Evolutionists have suggested that the lungfish is left over from the time when sea creatures were adapting to life on land. But their theory doesn't hold water, so to speak. Lungfish show little interest in moving to land. Besides, they lack important biological features that would make that move possible. What's more, the lungfish we find in the fossil record are exactly the same as those living today. There is absolutely no evidence of evolution here.
While the lungfish is an unusual creature, it is a testimony to the creativity and wisdom of the Creator, and offers no support at all for evolutionary speculations.
