Endosymbiosis is thought to have contributed to the evolution of eukaryotes. This process involved one prokaryotic cell engulfing another prokaryotic cell, leading to a symbiotic relationship that eventually gave rise to mitochondria and chloroplasts in eukaryotic cells. This event allowed for the development of more complex cellular structures and functions in eukaryotes.

How long ago did the eukaryotes evolve?
Eukaryotes are believed to have evolved around 2 billion years ago. This major evolutionary event led to the development of cells with a nucleus and other membrane-bound organelles, marking a significant step in the evolution of complex life forms.
Which organisms represent the common ancestor of all photosynthetic plastids found in eukaryotes?
Cyanobacteria are believed to be the common ancestor of all photosynthetic plastids found in eukaryotes. Through a process called endosymbiosis, cyanobacteria were engulfed by an ancestral eukaryotic cell, giving rise to plastids like chloroplasts. This event played a crucial role in the evolution of photosynthesis in eukaryotes.
What is the most important event in recent human evolution?
The most important event in recent human evolution is the development of agriculture, which led to the rise of civilizations and significant changes in human societies, lifestyles, and technology.
Which is the first event in translation in eukaryotes?
ANSWER: the small subunit of the ribosome recognizes and attaches to the 5' cap of mRNA ------------------------------------------------------------------------------------------------------- This answer bellow, appears all over the internet, but its wrong. I just took a quiz. -base pairing of activated methionine-tRNA to AUG of the messenger.
What did precambrian cyanobacteria do?
Precambrian cyanobacteria played a crucial role in the oxygenation of Earth's atmosphere through photosynthesis, which eventually led to the Great Oxidation Event. This event dramatically changed the composition of the atmosphere and paved the way for the evolution of aerobic organisms. Additionally, cyanobacteria contributed to the formation of stromatolites, which are some of the earliest known evidence of life on Earth.

What are the steps of evolution for man and whale?
Even in punctuated equilibria there are no distinct "steps" in evolution. But a single significant event can be pointed out common to the evolution of both lineages: the initial divergence of the ancestors of whales and humans from a common ancestor, thought to have taken place between 70 and 60 million years ago.
How long do scientist think evolution took?
took? Evolution wasn't an event. Its an ongoing process
What contributed to the event of Bleeding Kansas?
Slavery was an issue that contributed to the event of Bleeding Kansas. Bleeding Kansas was also known as the Bloody Kansas war.
What event contributed to the bleeding Kansas?
Slavery was an issue that contributed to the event of Bleeding Kansas. Bleeding Kansas was also known as the Bloody Kansas war.
Are there other theories that explain the same event as evolution theory?
No, there are no other theories but the theory of evolution by natural selection that explain so much about evolution.

How far did this event contribute to the end of World War 2?
As far as this event contributed to the end of WWII.
What event contributed to the spread of Buddhism?
The conversion of Ashoka the Great.
What is the most important event in recent human evolution?
The most important event in recent human evolution is the development of agriculture, which led to the rise of civilizations and significant changes in human societies, lifestyles, and technology.
Which came first Eukaryotes or oxygen Accumulation in the Atmosphere?
Oxygen accumulation in the atmosphere came before Eukaryotes. Around 2.4 billion years ago, photosynthetic bacteria began to produce oxygen as a byproduct of photosynthesis, leading to the Great Oxidation Event. Eukaryotes, which possess specialized organelles like mitochondria that utilize oxygen for energy production, evolved around 2 billion years ago.
