Summarize the following text with a simpler version: What do the bullet train and the kingfisher bird have in common?

However, nature, particularly through the evolutionary process known as natural selection, has the benefit of millions of years of trial and error, perfecting its design.

That is why it is logical that humans turn to it to design technology.

This type of innovation that emulates nature is called biomimetic design and has inspired many of our best creations, from trains to buildings.

Below our six favorite examples.

1. The bird train

Japan is famous for the incredible speed and efficiency of its trains.

However, when the famous bullet train began to circulate, they realized that there was a huge problem: with its speed of 300 km/h, every time it emerged from a tunnel it generated a roar that could be heard 400 meters away.

The train compressed the air in the tunnel in such a way that, upon exiting, it produced a large explosion of sound.

Traveling at 300 km/h, Shinkansen trains compressed the air in the tunnels and, upon exiting, produced a sonic boom.

Local residents protested the noise pollution and authorities were forced to fix the problem on Japan's high-speed rail network, or Shinkansen.

The answer came from Eiji Nakatsu, who, in addition to being an engineer, is a fan of birds.

The Nakatsu train, which opened in 1997, included a redesign of the front end inspired by the streamlined beak of the kingfisher.

But he also implemented improvements inspired by the feathers of owls, birds known for their silent flight, and the abdomen of the Adelie penguin, which glides with minimal resistance in the water.

2. Whale turbines

The humpback whale weighs 36 tons, but it is one of the most elegant swimmers, divers and jumpers in the sea.

As biomechanist Frank Fish demonstrated 15 years ago, these dynamic abilities are largely due to...<end_of_turn>
