400 million-year-old fossils linked to evolution of plant reproduction
The evolution process of plants has been a mystery. However, a team of scientists recently studied plant fossils and linked it to plant reproduction evolution.

evolution process of plants has been a mystery for scientists across world. Recently, a team of researchers studied plant fossils with an aim to discover origin period of evolution in plant reproduction. For purpose of research, team studied million years old fossils of plants kept at Smithsonian National Museum of Natural History in Washington.
study, which was recently published in journal Current Biology, focussed on scientists analysing how reproduction evolved in plants. According to reports, team studied 30 small rock fragments that were originally excavated from Campbellton Formation of New Brunswick, Cana. researchers n identified over 80 reproductive structures in plants which were n studied by scientists.

Difference in spores
y found out that while most of m consisted of spores, re was a difference in spores that prompted m to dig furr. Speaking to international media reporters, Andrew Leslie, a senior author at study elaborated that it was rare to get this many spongia with "well-preserved spores that you could measure".

Talking about reason for picking up topic, he said that study of plant reproduction is of increased labour, specialisation and complexity. However, he ded that someone h to begin process. He n said that se fossils gave an insight into period when evolution began in plants. According to researchers, fossil species belonged to Devonian geological period, spanning between 419,2 million and 358.9 million years ago.

Plant evolution is subset of evolutionary phemena that concern plants. Evolutionary phemena are characteristics of populations that are described by avers, medians, distributions, and or statistical methods. It includes study of genetic change and consequent variation that often results in speciation, one of most important s of riation into taxomic groups called cles.
