Green algae
The "primordial soup".
they have the same photosynthetic pigments.
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.
True
Scientists currently think that life got started between 3.8 and 3.5 billion years ago, probably less than a billion year after the formation of the Earth. It is certain that life existed by 2.7 billion years ago.
Scientists believe that plants evolved directly from a freshwater green algae called charophyte. There are two different types of charophytes, coleochaetales and charales, which strongly resemble earliest land plants.
from green algea that went into land plants which now represents present day chloroplast
Penguins evolved from birds. :)

90% of modern birds
why you think scientists probably want to leave wht they do open to revision?

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 think the milky way is stars, planetoids and other matter.
