To this day, 65% of our Earth - excluding land - is still shrouded in mystery, and 86% of the world's species are unknown. But science is constantly moving forward, and it seems that researchers always have something to surprise us with. For example, we recently discovered that doves can learn art and sheep can recognize your face.

We want to share the latest scientific research and amaze you with facts you may not have heard of yet.

1. Can you identify good paintings? Well, pigeons can. One Japanese study showed that trained pigeons can distinguish between "good" and "bad" pictures. Scientists have found that birds use color, texture, and pattern to decide if a painting is beautiful (according to humans). Of course, we are not talking about advanced skills, but pigeons, if trained, can acquire the ability to judge beauty.

Octopuses also have 3 hearts due to their structure: 2 hearts pump blood to the gills, and the third, the largest, is responsible for circulating blood to the rest of the body.

6. In the underwater kingdom, some males can give birth, and not just females. This "modest" list includes only 3 species: seahorses, sea needles and sea dragons.

In the future, the offspring of seahorses is carried by the male.
