An unprecedented fact is being investigated by several UK scientists and botanists.
The oldest tree in the UK, estimated to be over 5,000 years old, has started to change its sex. Undoubtedly, it is a "rare and unusual" phenomenon that scientists do not fully understand.
According to The Telegraph UK, the Yew (taxus) of Fortingall, in Perthshire, in central Scotland, has been registered for hundreds of years as male.
However, in recent years it has started to bear red berries, which suggests that part of it is beginning to change its sex.
Max Coleman, doctor of the Royan Botanic of Edinburgh, indicated that it is a strange event and that they are still understanding why the phenomenon:
It is evident that it is a male tree because wherever you look at it, you will see that it has male reproductive parts, except in a small area in the crown where we find fruits.
According to the specialist, males, such as Fortingall's, produce spherical structures of a yellowish green color that release pollen, while females produce red fruits, such as those recently observed in this specimen.
Although the phenomenon has been recorded in the past, Coleman sheds light on why this sex change occurs:
It is believed that if there is a change in the balance of the hormonal components, this sex change can occur. One of the triggers could be environmental stress.
"The tree looks healthy anyway," Coleman said, adding that they will take a closer look to see if the tree shows more changes.
