How did the development of the ozone layer allow life to develop on land?

Upper-level ozone is the product of the absorption of UVB rays by upper-atmosphere oxygen or O2. During the absorption process, the O2 molecule is split into two oxygen atoms. These atoms then recombine with an O2 molecule to create O3 or ozone.
The ozone layer in the upper atmosphere is therefore in a continual process of formation due to its constant bombardment (during daylight hours) by UV radiation. But O3 concentrations don't continually increase because the ozone molecule is unstable and gradually deteriorates back to O2 or oxygen.

∙ 13y agoWithout ozone, life on Earth would not have evolved in the way it has. The first stage of single cell organism development requires an oxygen-free environment. This type of environment existed on earth over 3000 million years ago. As the primitive forms of plant life multiplied and evolved, they began to release minute amounts of oxygen through the photosynthesis reaction (which converts carbon dioxide into oxygen). The build up of oxygen in the atmosphere led to the formation of the ozone layer in the upper atmosphere or stratosphere. This layer filters out incoming radiation in the "cell-damaging" ultraviolet (UV) part of the spectrum. Thus with the development of the ozone layer came the formation of more advanced life forms.

How did the ozone layer develop?
you stupid for not knwoing
When did ozone layer develop?
See "It is true that life could not have existed on land until the ozone layer formed about 2 million years ago Why does life on land require an ozone layer?" in the "Related questions" section below.
What are future problems does the hole in the ozone layer create?
Ozone hole is the thinning of ozone layer. Ozone hole can allow UV rays to pass through which can end life on earth.
Which part of the solar radiation is absorbed by the ozone layer?
The ultraviolet radiation is absorbed by the ozone layer. The ozone molecules do not allow only the ultraviolet radiations to pass through.
How do scientist believe that a ozone layer formed and what does it allow for?
Ozone layer is formed by UV rays. It allows us protection from the UV rays.
What is the development of ozone layer?
The ozone development is due to natural factors. UV is main of them.
How did the ozone layer develop?

Why do we have to protect the ozone layer?
We have to protect the ozone layer to allow human existence. This existence of ozone is the reason behind human survival.
What did the development of ozone in the stratosphere and oxygen in the atmosphere help do?
Development of ozone layer helps to avoid the UV from entering.
Describe the role of living organisms in producing the ozone layer and how the ozone layer affected the development of life on Earth since the prehistoric times?
Ozone has affected development in a good way. It has protected the earth.

The ultraviolet radiation is absorbed by the ozone layer. The ozone molecules do not allow only the ultraviolet radiations to pass through.
Why couldn't complex organisms develop the establishment of the ozone layer?
UV rays were the one's that hindered complex organisms. With the ozone layer, these rays were absorbed.
How do scientist believe that a ozone layer formed and what does it allow for?
Ozone layer is formed by UV rays. It allows us protection from the UV rays.
What are the good motivations about ozone layer?
Ozone layer must be protected to allow human survival. Motivation regarding human survival is enough for this.
What is the deffinition of ozone layer?
Ozone layer is a blanket of ozone molecules which are present in the stratospheric region of atmosphere. These molecules of ozone block the harmful ultraviolet radiations from the sun and do not allow them to enter the earth's surface.
