Prokaryotic fossils have been dated to 3.5 billion years ago, but it is not possible to determine by their shape if they were Archaea. Some lipids, consistent with eukaryotes or archaea, have been detected in shale dating to 2.7 billion years ago. The split between bacteria and archaea probably occurred earlier than that; the lipid remnants could be from either one or both. In light of genetic research since the 1960s, it is no longer held as a certainty that eukaryotes developed from archaea; they may have developed as separate, parallel lines of descent from primordial organisms. That is why the term "archaebacteria" has fallen out of use; Archaea are now classified as a separate domain of living organisms from Bacteria.
Archaebacteria, also known as archaea, first appeared around 3.8 billion years ago. They are one of the oldest forms of life on Earth and have evolved to thrive in extreme environments.
The archaebacteria are the only anaerobic species, who do not tolerate free oxygen.
No, archaebacteria are prokaryotic.
No, a mushroom is not an archaebacteria. Mushrooms belong to the kingdom Fungi, while archaebacteria are a separate domain of single-celled organisms that are distinct from both fungi and bacteria.
The former name for Eubacteria is "true bacteria" or "bacteria," while the former name for Archaebacteria is "archaebacteria" or "archaea." These terms were used prior to the reclassification of these groups into the domains Bacteria and Archaea, respectively.
Archaebacteria and monerans are both classifications of single-celled organisms, but monerans belong to the domain Bacteria while archaebacteria belong to the domain Archaea. Archaebacteria are known for living in extreme environments, while monerans are more commonly found in diverse habitats. Additionally, archaebacteria have unique cell membrane structures and genetic sequences that distinguish them from monerans.
Archaebacteria
The prokaryotic cells first appeared about 3 billion years ago. Scientists are not sure but perhaps a few of these bacteria could have been archaea. These appeared in the Pre-Cambrian Era
Archaebacteria
they were probably the first multicelluar life- forms
Archaebacteria
Archaebacteria lives in the bottom of the ocean. Archaebacteria lives in the bottom of the ocean.
one kind of archaebacteria is the methanogens
They have their own kingdom called Archaebacteria.
Yes, archaebacteria have a cell wall.
Both archaebacteria and eubacteria
archaebacteria consists of complex cells
Here are the 3 types of Archaebacteria Archaebacteria>>>>> 1. Methanogens 2. Halophiles 3. Thermoacidiophiles
