90% of modern birds
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.

Both. If you think about it, birds evolved from dinosaurs, and some think birds are the only living dinosaurs left.
They didn't but they do share a common ancestor. Looking at fossils, scientists have determined that bird evolved from small carnivorous dinosaurs. Both dinosaurs and crocodiles stem from a group of reptiles called archosaurs.

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.
No. Lots believe we evolved from apes, but think of the stupidity of it-- if that were the case, we'd be in the midst of turning into birds.
Dinosaurs as most people think of them are completely extinct. However, birds evolved from dinosaurs, and as such, are considered to be a group of dinosaurs. Since birds are still alive today, so are some dinosaurs. No dinosaurs other than birds are alive today, though.
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.
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.
