The extinction of dinosaurs 66 million years ago, which was caused by the impact of a large asteroid, was a pivotal moment in the history of life on Earth. The aftermath of this event allowed mammals to diversify and eventually become the dominant species on the planet. But what if the asteroid never hit?

If the Earth was never hit by the asteroid, the dinosaurs would have continued to thrive and evolve. Some species of dinosaurs may have gone extinct due to natural causes, but the majority of them would have remained as a dominant species. In this scenario, dinosaurs would have continued to evolve and possibly develop their own civilizations. With the dinosaurs in control, the evolution of mammals could have taken a different path. Since dinosaurs were already the dominant species, mammals would have remained small, nocturnal creatures with limited ecological niches.

The absence of the asteroid impact would also have meant that the Earth's ecosystem would have remained largely unchanged. The impact created massive fires, which led to the extinction of numerous species, and drastically altered the climate. Without the impact, the Earth's ecosystem would have continued to evolve naturally, with species adapting to changing conditions and competition with each other.

This would also have meant that the evolution of plants would have taken a different path. Without the asteroid impact, the Earth's vegetation would have remained dominated by ferns and cycads. It's possible that flowering plants, which evolved after the impact and helped to create a more diverse and complex ecosystem, may never have existed. This, in turn, would have affected the evolution of pollinators, such as bees and butterflies, which co-evolved with flowering plants.

The absence of the asteroid impact could also have affected the evolution of other species, such as birds. Birds evolved from dinosaurs, and without the extinction of the dinosaurs, birds may never have developed as a distinct group of animals. Furthermore, without the impact, sea levels would have remained relatively stable, limiting the opportunities for new species to evolve in the oceans. This could have prevented the evolution of many marine species, including whales, dolphins, and other cetaceans, which would have limited the diversity of life in the oceans.

It's also important to consider the impact that the absence of the asteroid impact would have on human evolution. Humans evolved from a lineage of primates that lived alongside the dinosaurs. Without the extinction of the dinosaurs, the evolutionary path of primates may have taken a different direction, and humans may never have existed. The presence of dinosaurs as a dominant species could have limited the opportunities for primates to diversify and evolve into new species, including our own.

In this scenario, the absence of the asteroid impact could have also affected the development of human civilization. The extinction of the dinosaurs allowed mammals, including primates, to diversify and eventually become the dominant species on the planet. This allowed for the evolution of humans, who went on to create civilizations and technology. Without the impact, dinosaurs would have remained dominant, and it is unlikely that humans would have ever evolved.

However, if dinosaurs did evolve intelligence, it's possible that they could have created their own civilizations. In this scenario, dinosaurs would have been the ones to develop technology, and create their own societies. It's possible that dinosaurs could have developed advanced civilizations, with their own cultures, beliefs, and technologies. This would have created an entirely different world, with dinosaurs as the dominant species, and humans may never have existed.
