The most likely scenario for the evolution of all amphibia, vertebrate animals who live partly in and partly outside the water, is the following:
At some time, all vertebrates were aquatic animals, spending all of their lives submerged in water. A combination of competition, scarcity of resources and predation would have caused groups of vertebrates to adapt first to seeking out ever shallower waters, and eventually even venturing out of the waters for periods of time - for instance for mating, reproducing or food gathering. Thus ambhibia would have evolved.
Some subset of these early amphibia would then have adapted even further, spending more and more time on land, eventually leaving the water altogether. From these groups have evolved all modern land-dwelling vertebrates.

What relationship does the poison dart frog has with biotic and abiotic factors in its environment?
Water, weather, mud, lots of things! Frogs need to stay moist so they need water/mud. The weather could wash them away, or dry them up. Just think of anything, and imagine how tree frogs are affected by them.
Why do frogs migrate?
Frogs adapt to live in their environment.
What do frogs do for earth?
They eat mosquitos, which carry a lot of sicknesses, but frogs dont get affected by them.
How are snakes different from frogs from their reaction to their environment?
Snakes eat frogs
What is the relationship between a tree frog and bromeliad?
Tree frogs have a commensalism relationship with frogs. Frogs live in bromeliads, but bromeliads are not affected at all.
What is the symbiotic relationship between a bromeliad and a tree?
Tree frogs have a commensalism relationship with frogs. Frogs live in bromeliads, but bromeliads are not affected at all.
What is the symbiotic relationship between the bromeliad and tree?
Tree frogs have a commensalism relationship with frogs. Frogs live in bromeliads, but bromeliads are not affected at all.
Does it really matter if frogs have deformities?
It might if the cause is a pollutant in the environment. If so, it could affect humans adversely as well.
Are frogs coldblooded?
Yes, frogs are cold blooded animals. This is because their body temperature changes with their environment.
Will chlorine kill frogs?
Yes, chlorine can be harmful to frogs and can potentially kill them if they are exposed to high levels of it in their environment.
How can frogs indicate changes in an ecosystem?
Because of their permeable skin, frogs are very sensitive to pollution. This means that when an area becomes polluted, frogs are usually some of the first animals to be affected.
Do frogs eat people food?
Frogs do not generally eat people food. Frogs tend to eat insects like flies and simple plants in their environment.
