Scientists believe that symbiotic relationships evolved through a process of co-evolution, where two species develop a relationship that benefits both of them. This can happen gradually over time as each species adapts to the presence of the other, leading to mutually beneficial interactions that enhance their survival and reproduction. The specific mechanisms through which symbiotic relationships evolved vary depending on the species involved and the nature of their interaction.
According to Lynn Margulis, eukaryotic cells may have evolved from symbiotic relationships between different prokaryotic organisms, such as bacteria and archaea. This theory is known as endosymbiotic theory, proposing that organelles like mitochondria and chloroplasts were once independent prokaryotic cells that were engulfed by a host cell.
Scientists believe that life on Earth evolved from simple molecules such as amino acids and nucleotides that formed in early Earth's environment. These molecules gradually combined and evolved to form more complex molecules and eventually led to the emergence of living organisms. This process likely occurred over millions of years through a series of chemical reactions.
Dolphin's symbiotic relationships involve lot and lots and LOTS of pooping in each other's mouth. Human think it is disgusting but for a dolphin that just another treat. Sometimes they penis fence to bond with each other. They like to jump around in the desert sommetimes and they enjoy climbing trees. It turns out that dolphins are really humans in a suit.

Plants and green algae have the same types of chlorophyll and carotenoids in their cells so scientists think plants and green algae have a common ancestor.
Some questions scientists still have about endosymbiosis include understanding the specific mechanisms by which endosymbiotic relationships are established and maintained, unraveling the evolutionary history of these relationships, and determining the extent to which endosymbiosis has contributed to the diversity and complexity of life on Earth. Additionally, researchers are also interested in investigating how endosymbiosis may have played a role in major evolutionary transitions.

They are thought to evolved from bacteria. Symbiotic living have turned them into organelles

Scientists think that penguins evolved from flying birds, similar to petrels and albatrosses, around 60 million years ago. Over time, they adapted to a more aquatic lifestyle, leading to their distinctive form and characteristics we see today.
because RNA depend to DNA.
Most evolutionary scientists today do not think that amphibians evolved from the lungfish. They do share some characteristics, but the lungfish has no hint of legs.
Scientists believe that chloroplasts evolved from ancient photosynthetic bacteria that were engulfed by ancient plant cells through a process called endosymbiosis. Over time, these bacteria formed a symbiotic relationship with the host cell, eventually becoming what we now recognize as chloroplasts. This theory is supported by the structural and genetic similarities between chloroplasts and modern photosynthetic bacteria.

Moss are plants, but are seedless. I think the previous poster mistaken Moss with that of Lichens. Lichens are symbiotic relationships between fungi and algae.
No they have bald heads so they have all the best friends
We do no know exactly what kind of lizard snakes evolved from, but scientists think it was related to monitor lizards.
Scientists think that all life evolved from the ocean, because that's where all life started. Animals come out of the ocean and through many generations, they get characteristics that help them survive.
