The minnows were first born after 60 million years in England

Two minnows

Two "living fossil" minnows grow male cones and females in the Ventnor Botanical Garden on the Isle of Wight, surprising the botanists.

Two minnows (Cycas revoluta), a primitive tree that once covered the Earth 280 million years ago, grew cones under a covered cliff at Ventnor Botanical Garden on Isle of Wight, England. Minnows are native plants in Japan that are usually grown only as indoor ornamental plants in England. But one of the minnows of the botanical garden produced the first outdoor hat in the country.

The minnows were widely distributed across England millions of years ago. Researchers found Jurassic tree fossils stretching from Wight Island to the coast of Dorset. Jurassic is also the period when the Earth's climate has a high natural carbon dioxide.

An outdoor nectar in Ventnor first grew male hats 7 years ago, but this year male and female hats appear on many different trees, helping botanists have the opportunity to pollinate and create seeds. like.

"For the first time after 60 million years in the UK, we encountered male cones and female hats appearing together. This is an authentic sign of climate change, not evidence from scientists but from plants. " Chris Kidd, manager of Ventnor Botanical Garden, said.

According to Kidd, the heat wave last summer, record high temperatures this year along with a series of warm winters have spurred trees to grow hats. The data of the botanical garden shows that the highest January average temperature of 100 years ago is still lower than today's lowest January average temperature. As a result, the 27-hectare botanical garden has a warmer climate than anywhere else in the UK, except for the Scilly Islands and can grow temperate plants, those that were unable to survive the winter.

Minnows are an evidence from the period before the emergence of flowering plants. In the homeland of Japan, Cycas revoluta pollinated with beetles. In the botanical garden, minnows have male cones that are slightly away from the tree with the female hat, so pollination will be done manually for about a week.

The minnows are the only genus left in the Jurassic family since they are considered "living fossils". All minnows are native plants in warm regions of the world, except Europe and Antarctica. The fossil of this Jurassic plant is very similar to that of minnows found today on continents.
