Watch the two videos below; The Tree of Life and Evolution in 5 minutes

In at least 100 words please answer the following questions.


1) Which stage of evolution do you believe was the most important in the evolution of life as we know it?

2) Why?



You may need to do further research on the internet to answer these questions effectively. If you do, please include any references you use.


DUE DATE: You must have completed this task by the start of your second class During Week 21 (9(8/10) Shocked

The most important stage of evolution in the entire process of evolution is the developement of cells because they are the seed that started the whole tree of life and without them being made life wouldnt be possible .
Although they were many important changes in evolution making us get closer to what we are today, it wouldnt have started without the cell.

Sorry I forgot some words Embarassed Embarassed . Also the most important stage of evolution was the cell because by being created it just not only created life it also could maintain it for a long period of time by nutrating all of the living species that were on the land. For example herbivores were alimented by plants which also they started by being a simple cell, showing that the cell was the most important stage of evolution because it didn't only made life but also maintained it by making smaller different living things like plants, algae, insects, etc to help one of the most important things living creatures need which is getting food and by that getting enough nutrients to help them in there long process of evolution.

Personally I think that the cell itself is the most important part in all of evolution. Not only now but also since "The Tree of Life" began. We could see there are animals in the water, on land, in the air, almost everywhere. Some animals are extinct some have survived until today and all of them have evolved. But they all started the same way, a cell, from which they evolved and keep on evolving. If you think about we are still made up of cells not the same one as in the beginning of evolution but there still cells. We can see in the second video that it takes time for things to evolve but if there were no cells none of it could be possible. Cool

I think that the most important stage of evolution is when the molecules start to join to make cells.
Because from the molecules and cells all started, the sea, the water, animals, etc. If the cells haved not developed nothing wold had hapened. fishes, insects, mamals, dinasours, water plants, all these started because one important thing, the cells. And talking about a special stage it is when the cells start to grow and develop in the sea and started to make life, such as; animals, plants, insects and bacterias. Something that it is interesting is that thinking that every thing, all, started only by one thing, the cell. From a cell a entire forms of live started to develop. Very Happy

I think that the most important stage of evolution is the formation of cells by the joint of molecules. I think that it is the most important because all living things started from a cell that dived and made new organisms, all life is reated. Since the formation of cells happened the tree of life begined, it begined in the sea and then they evolved and some whent to the sky and then some whent to land. The cell formation was the first stage of the "tree of life" or Evolution. In conclusion every thing in earth started from a tiny cell and then formed others.

i think the most important stage in evolution is the cell. everything started because of a cell so, without a cell, none of us would be alive.
although humans are now the ruling species on earth, they wouldnt be here if it weren't for a cell. it took millions of years to develop, and thanks to them, we have all the animals, plants, bacterias, etc. on our earth today.
the cell is a very important thing in the tree of life, because it is like the first seed planted, and thanks to that, the whole of the rest of the tree could grow.
even though the cell is very small, it is still the thing we are made up of and it is one of the things that helps us keep on living.
and that is why i think the cell is the most important thing in evolution and the tree of life

I think that the cell is the most important part in all of evolution. . We could diferent animals in the water, on land, in the air, all around the world, almost everwere. Some animals extinted, some have survived until today and all oof them have something to do with a single cell . They all started the same way with a cell. We are still made up of cells not the same one as the bigginig but they are still cells. In the second video it takes time for some things to evolve but if with out cells, nothing could be possible. tongue

I think that the most important stage in evolution is the very first cell that appeared and started to divide and change forming different species. This species continue evolving into new types and new skill along history.

The cell formation was the first stage of the "tree of life" or Evolution. If it wasn’t because of that first cell, humans, animals, bacteria’s and more wouldn’t be alive and there would be no living organism that could move, fed, reproduce, and basically live.

In conclusion everything in planet earth started from tiny cells that divides or change forming new ones with different characteristics.

Very Happy

The most important process of live is the cell because all living things started in just a little microscopic thing called the cell. If the cell will not exist the live because being made up of cell makes you a living thing , life simply will not exist . In the second video it is demonstrated that every living organism started evolving but these will not be possible if the cell will not exist. They join other cells to make a Organisms and then the organisems evolve to make a specie.

I think that is the cellular unit because is the basic unit for all living organisms this is for all starts in the cell, also was the start for the tree of life. This cell also has a define nucleus where it can contain genetic information to develop and to grow, this make them the start of the organisms when the cells reproduce asexualy or convining with each other.

The cell was the bigining of all of living organisms, if there where no cells all the rest will not exist, this is like a building dosn't have a first brick and this will collapse and fall down, this will occure with the living organisms.

I think that the most important part of the tree of life and evolution, is the cell.
This is becacuse, the cell is the beggining of everything else that we know today, and, besides from being the start of everything, it's the main thing which lets us evolve and support nature as it changes.
The cells aren't usually much thought of because of their almost insignificant size, but it was the very first existing thing, which lead the way for all the living (and non-living) things to be created, and then permited them to evolve so that it would survive all the changes.
This makes the cell the most basic, yet important, part of the tree of life and evolution albino pig

I think that the most important stage of evolution is the cell because its the begining of every living organisms, they could develop and created species that dothe same until now... different tipe of animals, all with different habitats, using their instint to survive in the animal kingdom.

The importance of the cell is impresive and simple. If cells never existed we wouldn't be here, but not only us, all the animals, insects, organisms, in fact everything .
summarising cells are the beging of evolution. cheers

In my opinion one of the most important stage in the evolution is the first cell that appeared and then this divides and start forming new types of species.

And also one of the most important thing in the second video its that the animal goes from his living space, that is the ocean and sea, and he started going to the land and that makes a the creations of ney types of animals because instead of develope fings like a fish, the started to develope hands like in a living land animal.

In conclusion we could say that the enormous creatures like animals that are living right now, they all started from a microscopic, little and tiny cell.

i think the most important part of the evolution is when the fish get out of the water because then it develope into the reptiles which later on are the dominant species on earth then into bierds and anphibians.it is the most important part because is whe all the species develop within the same species.
