Why do some species exist for millions of years and others a lot less?

A species’ survival depends on both its ability to adapt and its environment. Living things are continuously undergoing subtle changes to better suit the environment around them. During periods of particularly rapid climate change, the introduction of new diseases or the addition of new predators, some species cannot adapt quickly enough to survive. A genetically diverse species is more likely to survive, while those subjected to less change may survive for longer.

How do they make the Playstation 5’s graphics look so lifelike? Why didn’t they make PS4 or PS3 games look as good as in the recent demo?

Photorealistic graphics have been a dream of most gamers for decades, but the powerful hardware required is only now starting to become available. According to the CEO of Epic Games, Tim Sweeney, a truly photorealistic game would require 40 teraflops of computing power. The PS4 ‘only’ has 1.84 teraflops of power, and even the most powerful and expensive gaming PCs today struggle to achieve 30 teraflops.
