Lobster, butterflies and spiders share ancestors together

Recently, scientists have found fossils of creatures thought to be common ancestors of butterflies, spiders and lobsters.

Newly discovered lobsters, butterflies and spiders share ancestors together

Butterflies hover in the air, lobsters swim underwater and spiders live on the ground. Three species of creatures that seem unrelated to each other actually share the same root. Recently, the common ancestor fossils of all 3 species have been discovered and named Yawunik kootenayi.

Yawunik kootenayi is a marine creature dating from about 508 million years ago. It also means that they appear on Earth before the first dinosaur individual cries out for 250 million years.

Through initial research, experts found that Yawunik kootenayi was the ancestor of arthropods. They possess whiskers such as beetles and shrimp, four eyes split into two pairs, able to move with legs before swimming and hide under the hard shell when attacked.

At the same time, this marine creature has strong teeth that help them to beat the prey. As expected, Yawunik is also an ancient ancestor of present butterflies.

Butterflies, spiders and lobsters are all descendants of Yawunik kootenayi?

Fossils of Yawunik kootenayi were found by a paleontologist at the University of Toronto at Canyon Marble archaeological site. Their names themselves are based on the name of a local Kootenay tribe. In addition, the name Yawunik in culture here refers to an extremely terrifying carnivorous creature in legend.

Sharing more about this finding, Professor Jean-Bernard Caron of the research team said: 'Yawunik kootenayi is an extremely important discovery, holding a key position in the food chain and having a great influence on the system. Ancient ecology '.
