They know what triggers, they don't know what triggers it.

Neither animal, plant, nor fungus, the blob has been present on earth for nearly a billion years. It is one of the most primitive living beings and one of the simplest with its single cell. This organization fascinates researchers, Thomas Pesquet even slipped some in his luggage for the ISS to study its behavior in space. Everything about this funny creature.



Composed of a single giant cell, it has been around for over a billion years. Appeared on Earth long before plants and humans, it is one of the most primitive forms of life visible to the naked eye. From its learned name Physarum polycephalum, the blob, which has no fixed shape, can measure up to 10 square meters. Some look like big sponges, others like lichens or corals. Depending on the species, this unicellular organism can be yellow, but also white, black, gray, brown, blue, pink or red. Found mainly in the undergrowth of temperate zones, the blob thrives in the dark in a humid environment. Although devoid of mouth, stomach, eyes and legs, it eats (with a good appetite) bacteria, yeasts and fungi, digests, perceives light and moves at the speed of 1cm / hour, four times more quickly if he is hungry. Without a brain or nervous system, however, it is capable of developing complex strategies to ensure its survival.

Blob sponge
Neither plant, animal, nor mushroom, the blob is a curiosity of nature. Based on the successful work of ethologist and CNRS researcher Audrey Dussutour, this formidable documentary leads us to the discovery of a mysterious organism with astonishing capacities. In their laboratories, from Toulouse to Florence, from Hokkaido to Bremen and Boston, scientists specializing in disciplines as varied as neurobiology, biophysics, biology, computer science and robotics are multiplying their experiments to unlock their secrets. And perhaps pave the way, thanks to him, for new advances in medicine and artificial intelligence.

(sic! No one can date the appearance of life on this earth! All attempts have ended in failure or else source!

except for creationists, it is commonly believed that it started 3 or 4 billion years ago, which seen now does not change much. : Wink:
The origin of life on Earth remains uncertain. The oldest fossil microorganisms observed are dated at least 3,5 Ga (billion years ago) during the Paleoarchean. A study published in 2015 on carbon inclusions considered to be of organic origin assigns them an age of 4,1 billion years1 and more recently submarine water-repellent precipitates found in ferruginous sedimentary rocks of the greenstone belt of Nuvvuagittuq (Quebec) were interpreted as possible traces of life (filamentous organisms) at least 3,77 billion years ago and possibly 4,28 billion years ago2. If their biological origin is confirmed, life could therefore have appeared as early as the Hadean.

Nothing to do with any creationism, but with current scientific knowledge where it is only hypotheses of assumptions as shown in your article quoted from Wikipedia and which I therefore underline!

The origin of life on Earth remains uncertain. The oldest fossil microorganisms observed are dated of at least 3,5 Ga (billion years) during the Paleoarchean. A study published in 2015 on carbon inclusions considered to be of organic origin Assigns them an age of 4,1 billion years1 and more recently submarine water-repellent precipitates found in ferruginous sedimentary rocks of the Nuvvuagittuq greenstone belt (Quebec) were interpreted as possible traces of life (organisms filamentous) at least 3,77 billion years ago and possibly 4,28 billion years ago. Si their biological origin is confirmed, life pourrait therefore to have appeared from the Hadean.

this last sentence using two different tenses which presuppose a false certainty about the biological origin in question, or the use of the conditional highlights an uncertainty which should prevent using a present. The author should have written: "if the biological origin WAS confirmed" then, and only then life COULD .... Except that we do not know precisely, on the scientific level only! It is good for the theories as long as they are not confirmed, without scientific contesting.
for example a believer could write this: If their divine origin is confirmed, life pourrait therefore to have appeared 6.000 years ago.

nay! The fossils in question lose all biological and organic identity and these elements are mineralized by taking the "age" of the minerals in which they are included. So we measure the age of the mineral only.
There is a subject dedicated to this part and it is over 200 pages long, reread it to avoid repeating it!

It's not a blob but it looks like it...the magnetic slime robot...
