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.

Iran has sent five planeloads of food to Qatar, which is suffering shortages amid a regional blockade.
A number of nations, including Iran's major rival Saudi Arabia, last week cut ties with Qatar, accusing it of funding terrorism, charges it denies.
The land border with Saudi Arabia, through which 40% of Qatar's food comes, has been closed.
Meanwhile, mediators Kuwait said that Qatar was ready to listen to the "qualms" of its neighbours.
Is it worth it? We put cheesecake frap to the test.
The verdict from the nutritionists is damning. But does a cheesecake frappuccino taste good enough to merit the indulgence?
My advice is to only go there if you have unusually sweet tooth. I like my puddings, but this was a bit much even for me. The first hit is a winner, but it's downhill, slowly, from there. Each sip is a little less satisfying than the last, and maybe it was just all that sugar, but it isn't long before the rush is replaced by a creeping remorse. And half of the thing is still left.
The caramel version is far superior to the blueberry, too. If someone put a full caramel cheesecake through a liquidiser and scooped out the contents, it would probably taste something like this. Blueberry, on the other hand, has more of an artificial taste. It's like someone has tried to invent this drink in a lab, and while early results were promising, they're still in the testing phase. It isn't terrible, but something isn't quite right either.
So if you want an experience, go for a small, and opt for the caramel. But if you want a cheesecake, it's probably more satisfying, and not quite as unhealthy, to just order the real thing.
Important questions to consider
1. Where on the plane does my pet travel?
There are different types of travel available for pets:
- Manifest cargo
- Excess luggage in the hold
- Excess luggage in the cabin
Each option is safe. The feasibility of each option is based on the size and breed of your pet, the airline they are traveling on and country they are travelling to.
2. What is the difference between my pet traveling as manifest cargo or as excess luggage?
If traveling as manifest cargo, your pet is traveling in the front hold of the plane and can travel with or without you being on the same plane. The cost of your pets travel is based on volumetric weight, in other words, the size of their travel crate.
If traveling as excess luggage, your pet will be in the rear hold of the plane and must be traveling under the ticket of a human passenger. The cost of your pets travel is based on the actual (combined) weight of your pet in their crate.
3. What happens when my pet arrives in the country they are traveling to?
As soon as the flight arrives, your pet will be taken from the plane straight to the airport terminal.
If your pet is traveling as excess luggage, they will taken to the oversized luggage area in the arrival hall. Once you clear passport control, you will be able to collect them at the same time as your normal luggage. As you exit the airport via the ‘something to declare’ customs channel you will be asked to present your pets travel paperwork to the customs official and / or the vet on duty.
If your pet is traveling as manifest cargo, they will be taken to the Animal Reception Centre. There, their documentation will be reviewed by the staff of the ARC to ensure all is in order. At the same time, relevant customs formalities will be completed by staff based at the arriving airport.
4. How long does the travel paperwork and other travel preparations take?
This depends entirely on the location that your pet is traveling to. Your pet relocation compnay will provide you with an accurate timeline of how long the relevant preparations will take and at what point in the process the various steps must be taken.
In some cases they can get your pet ‘travel ready’ in a few days. In others it can be up to six months or more.
5. What vaccinations does my pet need to travel?
Regardless of where your pet is traveling, they will need certain vaccinations. The exact vaccinations they need are entirely dependent on the location they are traveling to. The one vaccination that is mandatory for every country your pet may travel to is a rabies vaccination.
Other vaccinations may also be necessary. These will be advised to you as relevant. In every situation, it is essential to keep your vaccinations current and to not miss a due date, even by one day. To do so could severely hinder your pets travel plans.

How much of your income do you need to save?
The more you save, the sooner you can retire. Tuan Phan, a board member of SimplyFI.com, says if you save just 5 per cent of your salary, you can expect to work for another 66 years before you are able to retire without too large a drop in income.
In other words, you will not save enough to retire comfortably. If you save 15 per cent, you can forward to another 43 working years. Up that to 40 per cent of your income, and your remaining working life drops to just 22 years. (see table)
Obviously, this is only a rough guide. How much you save will depend on variables, not least your salary and how much you already have in your pension pot. But it shows what you need to do to achieve financial independence.

Will the pound fall to parity with the dollar?
The idea of pound parity now seems less far-fetched as the risk grows that Britain may split away from the European Union without a deal.
Rupert Harrison, a fund manager at BlackRock, sees the risk of it falling to trade level with the dollar on a no-deal Brexit. The view echoes Morgan Stanley’s recent forecast that the currency can plunge toward $1 (Dh3.67) on such an outcome. That isn’t the majority view yet – a Bloomberg survey this month estimated the pound will slide to $1.10 should the UK exit the bloc without an agreement.
New Prime Minister Boris Johnson has repeatedly said that Britain will leave the EU on the October 31 deadline with or without an agreement, fuelling concern the nation is headed for a disorderly departure and fanning pessimism toward the pound. Sterling has fallen more than 7 per cent in the past three months, the worst performance among major developed-market currencies.
“The pound is at a much lower level now but I still think a no-deal exit would lead to significant volatility and we could be testing parity on a really bad outcome,” said Mr Harrison, who manages more than $10 billion in assets at BlackRock. “We will see this game of chicken continue through August and that’s likely negative for sterling,” he said about the deadlocked Brexit talks.
The pound fell 0.8 per cent to $1.2033 on Friday, its weakest closing level since the 1980s, after a report on the second quarter showed the UK economy shrank for the first time in six years. The data means it is likely the Bank of England will cut interest rates, according to Mizuho Bank.
The BOE said in November that the currency could fall even below $1 in an analysis on possible worst-case Brexit scenarios. Options-based calculations showed around a 6.4 per cent chance of pound-dollar parity in the next one year, markedly higher than 0.2 per cent in early March when prospects of a no-deal outcome were seemingly off the table.
