Scientists Reveal First Ancestor of All Flowers

A research team of scientists revealed that all living flowers eventually came from a single ancestor who lived about 140 million years ago, as quoted by the BBC.
 
The scientists incorporated various models of flower evolution with a feature data set of living flowers. From there the team was able to deduce the look of the ancestral flower. This flower has many cycles of petal-like organs arranged in threads, and bisexual.

Hervé Sauquet, of Université Paris-Sud, France, one of the authors of a paper published this week in Nature Communications said, "There is no living flower that looks exactly like this ancestor, why it is a flower that existed at least 140 million years ago Then and has grown into a variety of flowers that exist today. "

We are all familiar with the beauty of flowers the reproductive structure generated by about 90 percent of all living land plants. But their origin and early evolution is a mystery. This is mainly due to the lack of fossil flowers from the time period when the living flower ancestor has existed.
 
"The structure and organization of ancestral flowers remains mysterious," said Dr. Jason Hilton of the University of Birmingham, UK, who was not involved in the study. "For example, we do not know whether the oldest flowers are single or bisexual, or are they pollinated by Wind or insects. "

To reconstruct this first flower appearance, the scientists recorded features, such as petals and flower sepals from 792 living species.

They charted the distribution of this feature on the flower plant evolutionary tree that enabled them to build up a floral display of interest at key points in their history including the last ancestor of all living flowers.

The evolution of sex on flowers has been heavily debated. Flowers can be singular or bisexual and this study concludes early bisexual interest with both male and female organs.
 
"This study is important because it tells us how the intricacies of ancestral flowers are now, the search is to find something similar in the fossil record, whether this model is correct, only time and further studies will answer it," says Jason Hilton scientist.
