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.

What is different from archaebacteria and other kingdoms?
The archaebacteria are the only anaerobic species, who do not tolerate free oxygen.
Is archaebacteric eukarya?
No, archaebacteria are prokaryotic.
Is a mushroom an archaebacteria?
No, a mushroom is part of a much larger organism a fungus. Fungi are eukaryotes (large cell containing organelles) while archaebacteria are prokaryotes (small single cell without organelles).
What is the former name for Eubacteria and Archaebacteria?
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.
What are the differences between archaebacteria and monerans?
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.
When did the first Archaebacteria appear?
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
What arose first archaebacteria animals fungi plants protists?
Archaebacteria arose first, followed by protists, then animals, fungi, and plants. This evolutionary sequence is generally accepted by scientists based on evidence from the fossil record and molecular studies.
The archaebacteria were probably the first what?
they were probably the first multicelluar life- forms
What is the common name for the Archaebacteria kingdom?
The common name for the Archaebacteria kingdom is archaea.
What is one kind of archaebacteria?
one kind of archaebacteria is the methanogens
What kingdom does the archaebacteria belong to?
They have their own kingdom called Archaebacteria.
Do archaebacteria have cell wall?
Yes, archaebacteria have a cell wall.
What are three typess of archaebacteria?
Here are the 3 types of Archaebacteria Archaebacteria>>>>> 1. Methanogens 2. Halophiles 3. Thermoacidiophiles
Why is archaebacteria different from the other kingdoms?
The archaebacteria are the only anaerobic species, who do not tolerate free oxygen.
What are characteristics of the kingdom archaebacteria?
The archaebacteria is a unicellular organism without a nucleus. They are known to survive in extreme climates and environments. The first were discovered in 1977 in the boiling hot springs at Yellowstone National Park.
How long has archaebacteria been on earth?

Is archaebacteria present or extinct?
Archaebacteria is still present today and not extinct. Archaebacteria is a single cell microorganism and was once classified as bacteria.
