Species invasions are actually a very common occurrence on a global scale. Although there are countless species of organisms on the planet, these are distributed all over the world, with some species being endemic to certain areas and not present in others, and others having a relatively wide distribution. When some species appear in places where they would not have previously existed, this is when the species may become invasive.

Any animal is divided into two modes of memory: short-term memory and long-term memory, where short-term memory is something that is stored in the animal's brain for only a few seconds, usually such things are arbitrary events for the animal.

Since the discovery of the first exoplanet in the 1990s, scientists have found more than 4,000 exoplanets, some like the giant gas planets of our solar system, and others like earth-like planets. Some exoplanets may have very harsh environments, perhaps as hot as venus or mercury, or as extremely cold as other planets. Of course there are also exoplanets that may have relatively suitable temperatures, may be located in the habitable zone of a star system, are a potentially habitable planet, and may even be a living planet.

It happens to be the season when mosquitoes and flies go wild, but it is true that there are not as many flies as there are mosquitoes today. This has a lot to do with our improved sanitation today, after all, flies need to lay their eggs on manure pits and rotting food, while many rural toilets have now been converted to squatting, and the shorter disposal cycle for waste has greatly reduced their hatching.
