The question of which came first, the chicken or the egg, has puzzled people for centuries. But scientists may have finally solved the mystery. Nature possessed the tools to create eggs long before it made chickens, according to a new study.
It is believed the first life forms to appear on Earth were composed of a single cell, evolving over time to become more complex. But the process of how that happened is not well understood.
To look into this, a team from the University of Geneva studied Chromosphaera perkinsii, a single-celled species that was discovered in 2017 in marine sediments around Hawaii. It separated from the animal evolutionary line more than a billion years ago, making it a good case study to probe the evolutionary process that led to multicellularity – or life forms made of multiple cells.
The scientists discovered that Chromosphaera perkinsii, once they reach their maximum size, divide without growing any further – forming multicellular colonies with a three-dimensional structure that looks similar to the early stages of animal embryonic development.
That means embryonic development might have existed before the evolution of animals, meaning the egg came before the chicken, they say.
These colonies persist for around a third of their life cycle and included at least two different cell types, which scientists describe as a “surprising phenomenon” for the type of organism. That suggests the process governing complex multicellular development was already present more than a billion years ago, the researchers said.
“It’s fascinating, a species discovered very recently allows us to go back in time more than a billion years,” said Marine Olivetta, a laboratory technician at the Department of Biochemistry in the Unige Faculty of Science and first author of the study.
She said the study demonstrates that either the principle of embryonic development existed before animals, or multicellular development mechanisms evolved separately in C. perkinsii.
‘‘Although C. perkinsii is a unicellular species, this behaviour shows that multicellular co-ordination and differentiation processes are already present in the species, well before the first animals appeared on Earth’’, said Omaya Dudin, who led the research.

The Facility’s Versatility
Between the start of the 2020 IPL on September 20, and the end of the Pakistan Super League this coming Thursday, the Zayed Cricket Stadium has had an unprecedented amount of traffic.
Never before has a ground in this country – or perhaps anywhere in the world – had such a volume of major-match cricket.
And yet scoring has remained high, and Abu Dhabi has seen some classic encounters in every format of the game.
October 18, IPL, Kolkata Knight Riders tied with Sunrisers Hyderabad
The two playoff-chasing sides put on 163 apiece, before Kolkata went on to win the Super Over
January 8, ODI, UAE beat Ireland by six wickets
A century by CP Rizwan underpinned one of UAE’s greatest ever wins, as they chased 270 to win with an over to spare
February 6, T10, Northern Warriors beat Delhi Bulls by eight wickets
The final of the T10 was chiefly memorable for a ferocious over of fast bowling from Fidel Edwards to Nicholas Pooran
March 14, Test, Afghanistan beat Zimbabwe by six wickets
Eleven wickets for Rashid Khan, 1,305 runs scored in five days, and a last session finish
June 17, PSL, Islamabad United beat Peshawar Zalmi by 15 runs
Usman Khawaja scored a hundred as Islamabad posted the highest score ever by a Pakistan team in T20 cricket

It is a shorter stage, but one that will lead to a brutal uphill finish. This is the third visit in six editions since it was introduced to the race in 2012. Reigning champion Chris Froome won that race.
Four tips to secure IoT networks
Mohammed Abukhater, vice president at FireEye in the Middle East, said:
- Keep device software up-to-date. Most come with basic operating system, so users should ensure that they always have the latest version
- Besides a strong password, use two-step authentication. There should be a second log-in step like adding a code sent to your mobile number
- Usually smart devices come with many unnecessary features. Users should lock those features that are not required or used frequently
- Always create a different guest network for visitors
