Amphibians are vertebrates with strong leg bones that have developed to allow them to live on land. Also, during. Metamorphosis the amphibians gills are replaced with lungs.
They have a three-chambered heart that ensures that cells get the proper amount of oxygen, and they have 4 legs so they can move.
Modern Amphibians are actually active in water AND land. Back in prehistoric times, amphibians were the first animals to be able to move on water and land, but they had gills, which meant that they could not stay on land too long. So the answer to your question is that they had to grow lungs and scales (Amphibians evolved to reptiles).
Well most vertebrates have cephalization... this means that they developed a head structure allowing for a more advanced brain which of course means they have higher thinking capacity as well as having more advanced senses. Any organism that has cephalization is considered more advanced than its competition. However speaking about being successful land animals they probably aren't the most successful. The largest amount of land organisms is the insects and more specific the beetle.
lungs to breathe and feet to move and a protection from water loss
Some of the adaptations that enable the animals to move to the terrestrial environment is specialized body organs. The specialized body organs like the lungs.
personal areas got evolved.
The amniotic egg allows reptiles to reproduce on land, away from water.
This has been a long term debate for many, many years between those who believe in God, and those who believe in evolution.According to those who believe in creationism (God), they believeall animals, as well as humans, plants, minerals, etc. were created by God when He created the earth and all that's on it.According to those who believe in evolution, they believe animals, as well as all of the above evolved over millions of years. They believe that animals evolved as the temperatures and climates changed, which enabled them to survive these changes.
The heart is enabled to pump blood
The ability to lay hundreds of eggs. And probably the fact that they adapt to anywhere because there aren't that many different terrains underwater
First we need to see in what way we are different from other creatures. We walk upright, have opposable thumbs and relatively large brains. This has enabled us to fill a niche in the environment that no other creature could fill, and even create our own niche by altering the environment. Some say that another difference from other creatures is that humans have souls.The physical differences are easily explained. They are the result of evolution, enabling humans to survive and flourish in every continent. We can never prove we have souls, but if this is a difference from other animals it would be because God wished us to continue after we die, with him in heaven. But this can also be wishful thinking.For more information, please visit: http://christianity.answers.com/theology/the-story-of-creation
Banksia has a number of adaptations that have so far enabled the genus to survive despite dry, nutrient-poor soil, low rates of seed set, high rates of seed predation and low rates of seedling survival. These adaptations include proteoid roots and lignotubers; specialised floral structures that attract nectariferous animals and ensure effective pollen transfer; and the release of seed in response to bushfire.
Chariots enabled the transport of the army to be transfered from soldiers to animals.
It enabled animals to move more easily on land.
Yes, it is very true that the domestication of animals and plants through history has enabled humankind to improve their lifestyle. The domestication of animals and plants has improved agriculture, transportation, and medicine, among many other benefits.
It enabled people to work longer hours.

Photosynthesis allowed plants to spread over the earth, which enabled grazing animals to feed anywhere that plants could be found.
