The creature that has the shortest lifespan is the Mayfly.

Other creatures with the shortest lifespan are the Gastrotrich, Luna Moth, Mosquito, American Butterfly, Fly, Drone ant and the Indian Meal Moth.

The mayfly has a short lifespan of only 1 to 2 days because the sole purpose of the mayfly is to mate and they only live long enough to mate before they die.

However mayfly larvae called nymphs can live longer in bodies of water and can live for up to a year.

The animal that has survived all mass extinctions are Sharks and Coral

The animals that existed before humans are sponges, dinosaurs, birds, Megalania, Diprotodon, Procoptodon, Elephant birds, Moa, Haast's Eagle, Elasmotherium, giant ground sloths, Smilodon, Aenocyon.

Humans are the youngest species as humans also known as Homo Sapiens which is Latin for wise men are the ninth and youngest human species.

Humans have existed for at least 300 thousand years.

The origin of humans are Homo Sapiens that date back to 300 thousand years ago.

And while that is a long time ago it only represents only 0.007% of the entire history of plant earth which is 4.5 billion years.

Fossils and DNA suggest people looking like us humans, anatomically modern Homo sapiens, evolved around 300,000 years ago.

Surprisingly, archaeology – tools, artifacts, cave art – suggest that complex technology and cultures, “behavioral modernity”, evolved more recently: 50,000-65,000 years ago.

10,000 years ago: European males – 162.5cm (5 ft 4 inches).

A dramatic reduction in the size of humans occurred at this time.

Many scientists think that this reduction was influenced by global climatic change and the adoption of agriculture.

Humans or modern humans are the most common and widespread species of primate, and the last surviving species of the genus Homo.

They are great apes characterized by their hairlessness, bipedalism, and high intelligence.

A group of closely-related organisms that have common physical and genetic characteristics and are able to interbreed to produce fertile offspring.

As humans, we experience dramatically fewer hazards today than we did in our early evolution.

However, genetic studies indicate that we are still evolving.
