Evolutionary condition when everywhere was surrounded by water. when the condition changed than sea water is going to boil and these animals get more fast metabolic reaction. we know when metabolic reaction going to fast then required oxygen quantity is more high and when water boils then mixed oxygen quantity is very less (due to hydrogen bonds breaking).
Now the time when early vertebrates came out from water because the condition would be changed there are direct oxygen in atmosphere from that they fulfill required oxygen.

What is the difference between fish and birds?
Fish are aquatic vertebrates that have gills for breathing and fins for swimming, while birds are feathered, warm-blooded, egg-laying vertebrates with wings for flying. Fish live in water, while birds predominantly live on land and in the air.
Do frogs have only one lung?
No, They have two. There are no animals except some kinds of snakes that have only one lung.
When do tadpoles start to breathe air?
Tadpoles start breathing air through their skin and gills as they develop. They begin to come to the water's surface to take their first breaths of air when they are starting to grow hind legs and lose their gills. This transition usually occurs around 6-9 weeks after hatching.
What adaptation does a young baby frog have for breathing air?
A young baby frog is a tadpole. A tadpole is adapted to live in water. For breathing, it has gills, which helps it remain inside water until it grows up to become a frog. Gill are breathing organs of fish also, and the mode of living of a tadpole is similar to that of a fish. When it becomes a frog, it is capable of breathing both in air and in water. For breathing in air, a frog develops lungs and for breathing inside water the skin is used.
Examples of vertebrates that can float in water?
Some examples of vertebrates that can float in water include ducks, alligators, and hippos. These animals have adaptations such as buoyant bodies or air-filled structures that allow them to stay afloat on the water's surface.
Did birds first begin to fly in the pre-Cambrian period?
No. Birds are air breathing vertebrates, there were no air breathing animals in the Precambrian. The earliest bird fossils are found in rocks about 160 million years old in the Jurassic period.
What was the first air breathing animal?
The first air-breathing animal is believed to be the lungfish, dating back to around 400 million years ago. Lungfish have both gills and a primitive lung, allowing them to breathe air when necessary. This adaptation was crucial for early vertebrates transitioning from aquatic to terrestrial environments.
Why do snakes belong in the reptile group?
Snakes are cold-blooded, air breathing vertebrates that mostly reside on land and have scaly skin. These are all reptilian traits.
Is reptiles invertebrate?
There are different rumours; however invertebrates are said not having bones, but some scientists do not recognize Agnathaas vertebrates; in this case, because some extint agnathes had osseous tissue, some invertebrates would be said to have bones.
What is the breathing organ of tortise?
Tortoises have lungs as their breathing organ, just like most terrestrial vertebrates. They breathe air by expanding and contracting their lungs, allowing oxygen to be taken in and carbon dioxide to be released. This respiratory system enables them to survive on land.
What are the early signs of air pollution?
Smog, hazy air, odd smells, dis-coloration, breathing troubles, "thick" air, plant life dying off.
What type of respiration system do mammals have?
Mammals are air-breathing vertebrates. In mammals, respiration takes place in the lungs. Parts of the respiratory system include the lungs, diaphragm, bronchioles, bronchi, and trachea.
How do you know if you're a mammal?
The taxonomical class Mammals includes all animals (and people) that are air-breathing vertebrates, endothermic, have hair, three middle ear bones and in which females with you have functional mammary glands.
Why does an increascresed breathing rate accompany exercise?
it is because you need more air to exhale for excercising so thats why you begin to breath faster
Where does the respriatory system begin?
If you mean 'respiratory system'.....then it starts at the nose (breathing in is the first process before the air can reach the lungs for filtering out of oxygen into the blood stream). Breathing in is referred to as inhalation (of air), and breathing out is exhalation. Try browsing through the Biology categories (Human Anatomy, etc.) for the technical details, if you need them.
A vertebrate that lives in water and has fins?
You have the amphibians which are born in the water and grow into air breathing creatures, (such as the frog). Then there are the aquatic vertebrates which are wholly, or chiefly, water living creatures.
What do air do for us?
Air is used for breathing. Breathing is used to introduce oxygen into our system. Oxygen is necessary for life. Without breathing in air we would die.
