Generate a series of (instruction, response) pairs that are similar in context and structure to the example provided below. Each pair should consist of a concise instruction followed by an appropriate, detailed response. The instruction should pose a clear task or question, while the response should provide a comprehensive answer or solution that could be understood by someone with a basic understanding of the subject.

Example pair: 
Instruction: Brief me on what is going on in this news clipping: 

Thousands of Hollywood TV and movie screenwriters have downed tools after last-minute talks with major studios over wages broke down.

A Writers Guild of America (WGA) strike, the first in 15 years, saw more than 11,000 writers - 98% of voting members - walk out from midnight.

Tuesday's late-night shows are expected to shut down first, while forthcoming shows and films could face delays.

Picketing will begin on Tuesday afternoon, the Guild also said.

In 2007, writers went on strike for 100 days, at an estimated cost of around $2bn to the industry.

This time around, writers are clashing with the Alliance of Motion Picture and Television Producers (AMPTP) - which represents the major studios, including Amazon, Disney, Netflix and Paramount - in demand of higher pay and a greater share of the profits from the modern streaming boom.
Response: Thousands of screenwriters have set down their tools for the first time in 15 years. There will be a lot of financial repercussions, as these writers are demanding higher pay and a bigger share in the profits being made. 

Your task is to generate more pairs that maintain this level of clarity and detail. The topic is Summarization. Write a long text of instruction by yourself, then summarize the given instruction in a response. Ensure that the responses are informative and accurate, suitable for an educational context. 

Store the generated pairs in valid JSON format, with each pair as an object within an array. Each object should have two key-value pairs: "instruction" and "response". For instance: 

{"contents": [{"instruction": "text", "response": "text"}, {"instruction": "text", "response": "text"}, ...]} 

Remember to maintain consistency in the format and ensure the generated pairs are diverse and cover a broad range of subjects. You must return the response in the asked format and you must not add any additional text in your response.

Summarize the main points discussed in the following text about the evolution of life on Earth:

The evolution of life on Earth began approximately 3.8 billion years ago, with the earliest evidence of simple, single-celled organisms known as prokaryotes. These primitive life forms gradually evolved into more complex eukaryotic cells, which contained specialized organelles and membrane-bound nuclei. The first multicellular organisms emerged around 1 billion years ago, and the diversification of life accelerated during the Cambrian Explosion, a period of rapid evolutionary development that occurred about 541 million years ago. During this time, many major animal phyla appeared in the fossil record, including arthropods, chordates, and echinoderms. Plants also evolved from aquatic algae ancestors and gradually colonized terrestrial environments. Over the course of Earth's history, life has endured several major mass extinction events, which drastically reduced biodiversity but also paved the way for new evolutionary innovations and the rise of new species. The evolution of mammals occurred after the mass extinction event that wiped out the non-avian dinosaurs around 66 million years ago, allowing them to diversify and occupy a wide range of ecological niches. Humans, as a species of great apes, emerged relatively recently, around 6 million years ago. The evolution of life on Earth has been a continuous process of adaptation, diversification, and speciation, driven by natural selection and the interplay between genetic variation and environmental pressures.
