Darwinian evolution does not look ahead. It does
not do any planning
. So, where does the very effective design that we see in nature come from?

Biomimicry or biomimetics has recently become a success, that is, copying amazing design seen in nature, has become a flourishing research field.

Here’s a Phys.org story about frogs.

If you've ever camped by a pond, you know frogs make a racket at night; but what you might not know is how functional and regulated their choruses really are. Frogs communicate with sound, and amid their ruckus is an internally orchestrated system that lets information get through more clearly while also permitting collective choruses and time to rest. Researchers from Osaka University and University of Tsukuba sought to leverage this amphibious acumen for mathematical and technological aims. “

The story also says;

"We found neighboring frogs avoided temporal overlap, which allows a clear path for individual voices to be heard," study co-author Daichi Kominami explains. "In this same way, neighboring nodes in a sensor network need to alternate the timings of data transmission so the data packets don't collide."
