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.
How many more years were prokaryotes present before eukaryotes?
Prokaryotes were present for about 2 billion years before eukaryotes emerged. Eukaryotes are believed to have evolved around 1.5 to 2 billion years ago, while prokaryotes first appeared around 3.8 billion years ago.
When did the hypohippus appear and into what organisms did it likely evolve?
Hypohippus appeared during the Miocene epoch, around 23-5 million years ago. It likely evolved into modern-day horses and related equine species.
Protists are included among A prokaryotes B archaea C eukaryotes D bacteria?
Protists are single-celled eukaryotes.
What is another word for eukaryotes?

What must photosynthetic bacteria prove before any eukaryotes could evolve?
Oxygen Production.
The first fossilized eukaryotes date to about how many years ago?
2.1 billion
What comes between first eukaryotes and first terrestrial eukaryotes on a timeline?
The first eukaryotes were unicellular organisms that evolved around 2 billion years ago, followed by the first terrestrial eukaryotes that emerged around 1.6 billion years ago. Between these events, there were significant biological and environmental changes, including the development of multicellularity and adaptations for life on land.
How long ago did polar bears evolve into their own species?
They went to a different enviornment!!!!! Polar bears evolved from brown bears approximately 3 million years ago
For how long were prokaryotes the only kind of life on earth?
Prokaryotes were the only kind of life on earth approximately 2 billion years ago. They existed long before eukaryotes ever came into existence at all.
Which is smaller a eukaryotic organism or a prokaryotic organism?
Eukaryotes have organelles, like the mitochondria, which we think were prokaryotes a very long time ago. To fit these organelles inside their cytoplasm, the eukaryotes would have to be larger.
