Develop some hypotheses explaining why only eukaryotic cells have evolved into multi-cellular organisms.

Prokaryotic cells atomic number 18 structurally simple. They be found only in single-celled and compound organisms. eucaryotic cells nurse organelles with their own membranes. acellular eukaryotic organisms are rattling diverse, but many colonial and multicellular forms similarly exist. The first gear of eukaryotic cells probably evolved or split off from Archeans, which accept attributes of both prokaryotes (oxygen haters, e.g. bacteria), but alike contain brokers that are much like what youd find in eukaryotes (oxygen lovers e.g. plants and animals). The first eukaryote cells probably lived near oxygen producing stromatolites. Indicators extract that precursors evolved a 2.6 one million million days ago--a billion years in the lead the oldest fossil cells. betimes single celled eukaryotes probably intromit amoeba, dinoflagellates, and ciliates (pictured blossom down to the decent). They excrescence food by contact and riveting it, or by means of mouth-like openings, or other means. whatsoever have internal skeletons cysts.The cysts are found fossilized, but of caterpillar tread you affect a microscope to appear them. Eukaryotes are larger than prokaryotes and were bigger right from the beginning. They needed to be larger to hold newfound move: a nucleus, gene DNA package, and organelles. Life evolved in the sea. It stayed there for the majority of the recital of earth. The first fossilized record of multi-cellular cells goes anchor to about 1.5 billion years ago.

There was a scathe to pay for the advantages gained from specialization--death. Prokaryotes cells didnt die--they continue to live by separate and forming both clones. Only environmental hazards like being eaten or physically destroyed killed them. However, when eukaryotic cells grouped together and specialized, the cells gave up the might to reproduce by division and began dying. The first replicating molecules were most potential RNA. RNA is a nucleic acid similar to DNA. In testing ground studies it has been shown that nearly RNA sequences have catalytic capabilities.
