I think the most important part of evolution is when, the fish that turned into amphibians, started to get out of water. I know they had to go back to the water to lay their eggs but when they evolved and started laying hard shell eggs many amphibians turned into terrestrial animals. Those animals learnt how to survive out of the water and how to engage their dangers and thats how many other species evolved from being a simple amphibian into animals as we know them today. An impressive thing is that without the birds that survived the meteor in the dinosaur age (no one knows what really happened) we would not be here now because the tree of life would have been restarted from the begining and that would have taken 100,000,000 years more to evolve.

i believe that the most important and influent part on evolution is, when the amphibians turned into reptiles by laying solid
eggs because new species were created and life on land started.Then the reptiles turned to dinosaurs and were the
ruling species of the triasic era. Dinosaurs survived many years because of theirs scales and because they learnt how
to hunt each other and to defend themselves.But they were extint and mammals and birds lived because they were
warm blooded and had fur. Then the mammals evolved into apes and then into us the human.Without the change of the amphibians mammals we would not exist and without apes we could not be here.

I thought the most important part in evolution was in the beginning, when the prokaryotic cells became multicellular. Thats when everything started, as there would be no life on earth without the primary prokaryiotic cells to commence the process called evolution. Another important event that took place in evolution was the change from fish to amphibian, as they were able to breathe air and come out of the water, make eggs and hatch them near water. The process of Evolution is long, but has helped us become what we are today. Evolution never stops, not only in animals to adapt, but in technology, lifestyles, etc. Its very important for survival and success in a habitat.

I think that the most important part of the evolution of life as we know it is when chemicals molecules started to come together and form microscopic organisms, because as the first video says all life is related. As all life is related without those organisms, life wouldn't be as it is now a days. Another important part of evolution of life is when sea animals crawled out of the sea and developed feet and lungs to survive out of the water and adapt to the earth's conditions. This way reptiles, amphibians, birds, mammals and many other species appeared on earth.

I think the most important part of evolution is right at the beginning when chemical molecules joined together and formed cells. I think this because it gave origin to all animals as we know them today. This gave them the possibility to develop and become what we are today. It then developed into the tree of life with many different types of species living in the sea, land, air and water. The cells are the seed of the tree of life and thanks to them we have the variety of living creatures on earth today.

I believe that the most important stage in the evolution of life as we know it is when it all began, when chemicals began to come together to form atoms and then molecules and cells. I think this is the most important stage because if it had not happened we would not exist on earth or at least not so developed as we are now. Another reason to say that this stage is the most important is that if the chemicals had not come together variation would not had happened and we would be all equal.

I think that the most important stage on the evolution of the video "Tree of Life", is when after the catastrophy of the meteors happened, wings and feathers started to grow on the dinasours that survived the catastrophy. It is the most important stage because, when the wings started to grow they were more safe and more protected than if they were in the grown with more risk to be eaten, also when the wings apeared they were with more advantage from the other criatures in the grown because of their agility to scape from other big or carnivorus criatures and the agility to grab or still something from others. In conclusion the evolution from dinasours that walked in the dangerous bottom of the earth too dinasours that evoluted to form a big flying criature that have more advantages and were more protected than the other criatures in the grown was a important stage in the evolution of life, and because of them some other animals that exists now a days have life.

I think the most important stage of evolution is when the cells started to divide themselves and different organisms began to appear and started to form different shapes of life, like chains and circles because these cells were the first multicellular organisms and they were more complex and specialised than before. It is also very important because it created the variety in living organisms, so very slowly different animals began to evolve into different species living in different environments (sea, sky and land.) Thanks to evolution every living thing is different from other species and is not just a cell in the sea.

I think the most important part of evolution was just when it all started when the chemicals joined to form cells beause that gave origin to all life as we no it and life would not exist if that had not happened. This event was the start of the development of evolution and it all happened because of the combination of chemical molecules This is how all life forms from sea, air a land develop and how the tree life was formed so in a way te creation of cells is the seed of the tree of life an the tree wouldn't exist if it wasn't for the seed

I think the most important stage is the begining one the creation of the cell because if that stage wasn't present the whole world as we know it would not be the same. It could be cleane, i know, but other animals wouldn't exsist so earth would be a deserted, dead planet.

For me, the most important stage of evolution is when complex chemical molecules started to join together to form microscopic cells, and as the beginning of the video says, all stated in the sea but all life is related. This is very important because at the beginning of the planet earth there was nothing and suddenly these cells started to join together and lead us to the world we live in now. Another important thing is when fishes turned into amphibians and could learn how to breathe outside water, laid their eggs near water. All this process known as evolution was very long but was what allowed us to live in the world we know.

I think that the most important part of evolution is when the sea animals started to leave the sea and tried to live on land. That made them develope: legs,wings,longs,etc. In the first video the man said that it all began when litlle complex chemical molecules began to get together and form cells. Another important part was when particalls got together and formed atoms and then molecules,etc. The video said that all life is related which means for me that we are all made of the same basic things.
