Hermaphrodite flower considered mother of all flowers


The study conducted by researchers tells us about the first flower to appear along the path of plant evolution. During the time of the dinosaurs, was a hermaphrodite with petal-like organs arranged in concentric circles. Experts believe that land plants emerged from ancestral water plants about 470 million years ago

More than three billion years after the first life. Emerged when Earth was about a billion years old. The oldest-known fossils of flowering plants date from about 140 million years ago. During the age of the dinosaurs which went extinct some 66 million years ago.

The first seed plants that includes flowering plants and cone-bearing ones likely emerged. About 320 million years ago, when there were diverse animals on land and at sea. But not yet dinosaurs, mammals or birds.

Modern flowers with tepals rather than petals.

Since then, the first flower has evolved into at least 300,0000 species. It include almost all plant types used by people for food, medicine and other purposes, said the research team. Flowering plants represent about 90 percent of all plants on Earth. The bloom had both male and female reproductive organs at the center. Surrounded by multiple layers or whorls of petal-like parts called Tepals. Arranged in sets of three per layer. Based on the largest dataset of flower traits ever assembled from 792 existing species. And challenges scientific assumptions that the ancestral flower would have had its sex organs and “petals” arranged in a spiral.

Most flowers today have four whorls the outer leaves or sepals, followed by the petals, which enclose the male organs called Stamens. And the female organs or carpels at the centre. This is the first time that we have a clear vision for the early evolution of flowers across all Angiosperms the scientific term for flowering plants. The ancestral flower likely did not have separate sepals and petals, instead sporting tepals a mix between the two around the sex organs at the centre.

Hermaphrodite marijuana plants develop both male and female flowers. While it is a natural feature of the cannabis plant, it is an undesired trait when growing marijuana for consumption, since there is a great chance to obtain a plant full of seeds, what seriously reduces the quantity and quality of the final product.

The team combined DNA data and a vast library of plant traits to compile a detailed evolutionary tree leading back to the last common ancestor.
