Yes, prokaryotes are generally considered to be older than eukaryotes in terms of evolutionary history. Prokaryotes are believed to have appeared on Earth around 3.5 billion years ago, while eukaryotes are thought to have evolved from prokaryotic ancestors around 1.5 billion years ago.

Approximatley how much older are prokaryotes than eukaryotes?
Prokaryotes are believed to have appeared around 3.5 billion years ago, while eukaryotes are estimated to have evolved around 1.6 billion years ago. Therefore, prokaryotes are approximately 1.9 billion years older than eukaryotes.
Characteristics that appear in recent parts of a lineage but not in its older members are called?
Characteristics that appear in recent parts of a lineage but not in its older members are called derived traits or evolutionary novelties. These traits represent evolutionary changes that have arisen in a particular branch of a lineage over time.
Where protist were the first prokaryotic organisms on Earth?
The oldest life fossils are very simple - prokaryotic no doubt and not that different from many of today's prokaryotic cell structure. Evolution in general seems to be an increase in complexity. Thus the first cells would logically be prokaryotic, or at least noneukaryotic. This is because prokaryotic cells are much simpler than prokaryotic cells which contain multiple membranous organelles to complicate their structure. Note that just because the oldest life fossils are prokaryotic does not prove that they preceeded the eukaryotes or that they were the VERY FIRST life on earth. Can there be simpler life than prokaryotes one wonders? However, no fossils have been found that are older than those 'first' prokaryotes, and as I have said it would be illogical for more complex eukaryotes to precede the simpler prokaryotes. The oldest fossils therefore (between 3.5 and 3.8 billion years old) are thus accepted as both the first life and prokaryotic.
How do scientists use scientists use structural similarities to determine the evolutionary relationship?
Scientists use structural similarities, such as homologous structures and similar biochemical pathways, to determine evolutionary relationships. These similarities suggest a common ancestry and can help scientists infer how different species are related to each other. By comparing the presence and arrangement of these structures among different species, scientists can construct evolutionary trees to understand the history of life on Earth.
Are bacteria a prokaryotic or eukaryotic?
Bacteria are prokaryotic (along with the older domain Archaea).Prokaryotes have no cell nucleus or membrane-bound organelles, are typically small and unicellular, and have circular ("plasmid") DNA.Eukaryotes, by contrast, have a cell nucleus and various other membrane-bound organelles, can be uni- or multicellular, and have DNA bound tightly into chromosomes.These are not the only differences between prokaryotes and eukaryotes, but they are some simple ones for deciding between the two types of organisms.

Approximatley how much older are prokaryotes than eukaryotes?
Prokaryotes are believed to have appeared around 3.5 billion years ago, while eukaryotes are estimated to have evolved around 1.6 billion years ago. Therefore, prokaryotes are approximately 1.9 billion years older than eukaryotes.
Why are prokaryotes older then eukaryotes?
Prokaryotes are considered older because they appeared in the fossil record earlier than eukaryotes. It is believed that the simpler structure of prokaryotic cells made them better suited for survival in the early Earth conditions. Eukaryotic cells with their complex internal structures evolved later.
Approximately how much older are prokaryotes than eukaryotes?
Prokaryotes are estimated to have been around for about 3.8 billion years, while eukaryotes are thought to have evolved around 1.6 billion years ago. Therefore, prokaryotes are approximately 2.2 billion years older than eukaryotes.
Are prokaryotic cells older than eukaryotic cells?
Yes, prokaryotic cells are generally considered to be older than eukaryotic cells in terms of evolutionary history. Fossil evidence and molecular studies suggest that prokaryotes appeared on Earth around 3.5 billion years ago, while eukaryotes evolved much later, around 1.6 billion years ago.
Compare and contrast prokayotes and eukaryotes?
Prokaryotes are older, more basic in function and shape, do not contain a true nucleus or any membrane-bound organelles, unicellular (for the most part - some bacteria have multicellular stages in their life), and consist of bacteria and archae (old bacteria). Eukaryotes can be uni- or multi-cellular, have a nucleus and membrane-bound organelles, are generally more complex in shape and function, much larger than prokaryotes and evolved later in history. These are just some basic comparisons.
Is the oyster or the clam older in the evolutionary chain?

What is the difference between an animal cell and bacterium cell?
There are a few. The biggest one is that animals are eukaryotic (having a membrane-bound nucleus) while bacteria are prokaryotic (their DNA just sort of floats around in the cytoplasm). While prokaryotes are older, eukaryotes are generally seen as genetically more advanced.
What Photosystem is older in terms of evolutionary history?
Photosystem II is older in terms of evolutionary history compared to Photosystem I. Photosystem II is thought to have evolved before Photosystem I as it evolved to oxidize water in order to provide electrons for the electron transport chain, which Photosystem I then uses to reduce NADP+ to NADPH.
Can you Compare the updated classification of protists with the older one?
The updated classification of protists uses molecular data to group organisms based on evolutionary relationships, leading to a more accurate and comprehensive classification system. In contrast, the older classification relied heavily on morphological characteristics, resulting in some inaccuracies and uncertainties in the relationships between different protist groups. The new classification system has helped to clarify the diversity and evolutionary history of protists.
Which is older form of life the eubacterium or the archaebacterium?
eubacteria because they are the most common prokaryotes. if something was an older form it would be more common because its been around for a long time.
What could be the first organisms?
[1] There's no all-across-the-board agreement. Some scientists believe the first organisms to be amoebae and fungi, others bacteria. The former are called eukaryotes, because they have nuclei. The latter are called prokaryotes, because they have no nuclei. Those who believe the eukaryotes were first call chloroplasts and mitochondria among the first organisms. Those who believe the prokaryotes were first call the monera among the first organisms. [2] A common assumption has been equating earlier appearance with simplicity. It favors the prokaryotes, for their lack of the more complex nuclei. [3] But a growing argument has been equating earlier appearance with complexity, later appearance with streamlining into simplicity. It favors the eukaryotes, for their nuclei which the projaryotes supposedly jettisoned in their efforts to streamline. [4] Another assumption has been linking earlier appearance with areas of heat, deep within the oceans. It favors the prokaryotes, which handled high temperatures much better than the eurkaryotes. [5] The oldest known fossils date back 3.5 billion years. They're the stromatolites of Glacier National Park. And they contain cyanobacteria microbes. [6] Some scientists say that there's an even older first organism that was the ancestor common to both eurkaryotes and prokaryotes. But they disagree on whether that ancestor evolved first into the former and then the latter, or vice versa.
