Perhaps one of the first paradoxes we all encounter in life Did the egg come from the chicken or the chicken from the egg? is the question. Ultimately, a chicken may hatch from the egg. Chickens also hatch from eggs. According to scientists, the answer to this question lies in the past.

According to a new study, life on our planet is expanding before the first animals Started using embryos. It was revealed that a single-celled creature living in the mudflats at the bottom of shallow seas developed a structure similar to animal embryos during the reproductive process. The reproductive process of this creature resembles cell divisions in embryos.

Sharing like an animal embryo

Single-celled organisms generally reproduce by cell division. Chromosphaera perkinsii This creature, called Morula, first forms two cells adhering to each other, similar to cell division in embryos, and then forms a mass of empty cells known as morula.

Researchers found that a similar process took place in multicellular organisms The fact that a cell with this structure later becomes independent and reproduces shows that a similar developmental process is possible. Because Chromosphaera perkinsii, called ichthyosaur Part of the live band. Creatures in this group diverged from multicellular submerged lizard species millions of years ago.

Scientists say that this process, which also occurs in animals, It may date back to ancient times and thinks that eggs could have formed before multicellular creatures. However, they also argue that these structures require further investigation.
