Intelligent Design – Pollywogs

“’Everything is sort of built in a way that to me suggests intelligent design.’ Novelist Stephen King, in an interview with National Public Radio, on his belief in God.  He said evidence for God was in the stars, sunrises and sunsets, and ‘the fact the bees pollinate all these crops and keep us alive and the way that everything seems to work together.’”  World magazine, June 29, 2013, p. 24.

You probably know that God created many birds and mammals with incredible parenting skills. But you may be amazed what effort a tiny amphibian from the remote forests of Central America makes to ensure its offspring’s survival.

Many frogs species simply lay their eggs in water and leave the scene. Any eggs that don’t get eaten hatch into tadpoles that must fend for imagesthemselves. Not so with poison dart frogs of Central and South America! Devoted parents, they remain with the eggs until they hatch. Since they lay their eggs out of the water, they keep coming back to ensure that the eggs stay moist. Once the eggs hatch, either one or both parents carry the tadpoles on their backs to a nearby water hole, where the young complete development.

Strawberry poison dart frog moms take parenting to an even higher level. Laying fewer eggs than most frogs, they invest considerable time and energy to make sure their three to nine tadpoles survive. Such dedication is no accident.

Before the female lays eggs, however, a male suitor courts her by calling. Only males call—a surprisingly loud vocalization for such a tiny frog. If she shows interest, the female follows him, as he continues to call, to an egg-laying site of his choosing, often at the end of a leaf.

After the eggs are laid and fertilized, for the next seven to twelve/days the father diligently keeps the eggs moist until they hatch. He must. If they dry out, they won’t survive. When the eggs hatch, the father’s role is finished, and the mother takes over “child-rearing.”

First, the mother squats down and allows a single tadpole to wiggle up onto her back. Then shejcearches low and high for a suitable small body of water in which to place her youngster. Sometimes she already seems to have a place in mind. Other times she will carry the tadpole around for days until she finds just the right spot.

When she finds that perfect place— often a rain-filled leaf “axil” (the upper angle between a leaf and the stem) of a bromeliad plant—she backs into the “pool,” and the tadpole takes its first swim. The mother knows enough to put only one tadpole in each pool, a good thing since the stronger siblings might cannibalize the weaker ones.

Next, this “super mom” does some-thing that is truly extraordinary. She somehow remembers or senses where she dropped off each tadpole. For six to eight weeks, she regularly revisits them—often every day—to lay unfer-. tilized eggs for her youngsters to eat, their only source of nourishment until their metamorphosis is complete.

God’s awesome care can be seen everywhere, even in the remote forests of Central America, where lowly straw­berry poison dart frogs faithfully care for their young.

“His invisible attributes are clearly seen, being understood by the things that are made” (Romans 1:20). ■
