The oldest evidence of sexual reproduction has been found in a flowering plant dating back 100 million years.
One of the 18 tiny flowers of the plant, which were embedded in a piece of amber found in Burma, were in the process of making new seeds for the next generation, the BBC reported.
The US-German team which found the piece said that the main aspect of this discovery is that it presents a new look at the biodiversity of early flowering plants, which caused an enormous change in biodiversity on Earth.
The flowers date back to the mid-Cretaceous Period when dinosaurs walked the Earth.
The findings have been published findings in the Journal of the Botanical Institute of Texas.
