The most recent common ancestor to all living salamanders certainly had at least aquatic larvae, and probably an entirely aquatic life cycle, much like a hellbender.
gradually gradually
The population has evolved into two separate species if the species in question no longer interbreed.
Frogs evolved from salamander-like amphibians. They exist since the Triassic, some 200-250 years ago.
I believe that the hypothesis has something to do with the evolution to the varying ecosystems .in which salamanders live. the aquatic salamander evolved most likely to benefit in its area. A great area that may be referred to for this is Darwin's theory, of natural selection
Animals and plants have separate evolutionary paths. They both evolved from a common ancestor but took different paths in their development. Plants evolved from ancient photosynthetic bacteria, while animals evolved from multicellular organisms that were different from plants.
No. Lizards evolved from a separate group of reptiles and, as far as reptiles go, are not closely related to dinosaurs. The modern "evolved form" of the dinosaurs is actually the birds.
The finches evolved differently by living on separate islands.
It was more of a discovery than an invention. And it was not a single person who discovered it. The law gradually evolved over time.
English gradually evolved from other languages, it wasn't invented at a specific time. Consequently, there is no first English word, just lots of words from old Norman and French and Latin gradually changing into what we call English.
David and Jamie's relationship evolved over time. Evolve means that something changed gradually. Sometimes when things evolve they are no longer recognizable.
I don't think there is such a thing. Our modern concept of energy evolved gradually over time; no single person can be credited for discovering it.
Guinea pigs are believed to have evolved from a group of rodents called cavies. These ancestral species lived in South America and gradually evolved into the domestic guinea pigs we see today through selective breeding by humans.
