pai nu au fost mai intai organismele unicelulare? e o traducere gresita? ma documentez si poate reviu

as fi foarte curios sa aflu cum au definit domnii cercetatori notiunea de "vietuitoare". bacteriile nu sunt vietuitoare? s-au referit la ceva vizibil? la ceva care...gandea....habar n-am. mi-ar placea sa ma lamureasca ei, pentru ca pentru mine este un mic mister cum prima vietuitoare poate fi ceva cu dimensiuni in cm.

Intrebarea e... ce specialisti au facut cercetarea asta? Pentru ca, sper ca nu ma insel, dar nu cumva acesti specialisti ar fi trebuit sa scrie acele carti pe care le-au citit? Poate au facut un model matematic, o simulare computerizata ceva pe baza acestor carti, dar asa?
Bre ziare.com, ia pune mana si informeaza complet aici, ca ne bagi in ceata!

Este vorba de primul "ANIMAL" nu de prima vietuitoare, unde animal inseamna, citez en.wikipedia.org: "Animals are a major group of multicellular, eukaryotic organisms of the kingdom Animalia or Metazoa. Their body plan becomes fixed as they develop, usually early on in their development as embryos, although some undergo a process of metamorphosis later on in their life. Most animals are motile - they can move spontaneously and independently. Animals are heterotrophs - they are dependent on other organisms (e.g. plants) for sustenance.[...] Animals have several characteristics that set them apart from other living things. Animals are eukaryotic and usually multicellular[2] (although see Myxozoa), which separates them from bacteria and most protists. They are heterotrophic,[3] generally digesting food in an internal chamber, which separates them from plants and algae. They are also distinguished from plants, algae, and fungi by lacking cell walls.[4] All animals are motile,[5] if only...

Embryos pass through a blastula stage, which is a characteristic exclusive to animals."

Nu este vorba de vreo meduza cu creasta, ci de faptul ca aceste meduze aveau cilii inotatori, pare-se inglobati in membrana aia spaima, in forma de pieptene.

Sper ca v-am lamurit macar un pic. (revenire la forma initiala)
