Hello, Soulraider

What I liked

This is an interesting summary of the evolution of life on Earth. It explains the key phases of that process from the beginning to the dominance of mammals.

What might need work

It's a lot to take in as one big paragraph. Consider breaking this into themed paragraphs, grouping the information you wish to communicate by clear phases, eg. Precambrian, Palaeozoic, Mesozoic, Cenozoic, maybe using those as headers for each. Bring in dates to help the reader understand the vast time scale off this process, eg. the Earth was formed roughly five billion years ago, but life began around two billion years ago, and the first clear fossils appeared 542 million years ago so marking the beginning of the Palaeozoic.

Since this is an article, consider citing some sources for your information, even if it's vague, such as "geologists have discovered" or "palaeontologists have unearthed fossils" etc. Consider naming some specific plant and animal types, such as the first appearance of fish, the first land animals, the first birds etc. Mention other key facts, such as the barrier between Mesozoic and Cenozoic being marked by an extinction level catastrophe believed to be a meteor strike that led to the extinction of ninety-nine percent of species on Earth, including most dinosaurs, providing the opportunity for the explosion of mammalian species in the Cenozoic.

Also mention more about conditions. You do mention the production of oxygen by proto-plants, but this would have been clearer if you'd mentioned the higher percentages of carbon dioxide before this. Talk about the organic soup, ie. the conditions necessary for the first appearance of life, such as water and certain minerals and chemicals present in that water, and the key role of carbon with its unique ability to form four chemical bonds and Benzine rings essential for organic chemicals to exist.

Link all this to modern concerns to make it more relevant to people, eg. by stressing the importance of the delicate balance in the environment at each stage in the evolutionary process.

Thank you for sharing!
