The average time a species spends on Earth before going extinct is difficult to determine, as it can vary greatly depending on the species and its environment. Some species have existed for millions of years, while others may go extinct relatively quickly due to various factors such as habitat loss, climate change, or competition from other species. Extinction is a natural part of the evolutionary process, but human activities have accelerated the rate of extinction in recent times.
It is classified as extinct when there are NO animals of that species left, not one.
It is hard to calculate the number of animals that have become extinct since 1681 since some species went extinct before scientists knew they existed. What is known is that more than 90 species of birds and hundreds of species of mammals have gone extinct since then.
It is hard to determine exactly how many animal species are extinct because some species become extinct before scientists even know they existed. As far as science can tell, there are over 900 extinct species.
Flies will likely continue to evolve for another 1.1 billion years before extinction. The current species will have gone extinct (replaced with a new species of Fly) long before then.
A lot of things will have had to have gone extinct before something like the redheaded woodpecker will disappear.
None did. Titanoboa went extinct long before the ice ages began. Species go extinct fairly regularly do to environmental changes and competition with other species.
Any species that goes extinct has a last surviving individual. So yes, there was a last surviving saber toothed cat before they went extinct.
there have been too many to count, like animals that were extinct before we were here
Over the entire evolutionary history, species can be expected to last on average about 2 million years
Over hunting by humans Pollution Loss of habitat Loss of food supply Disease Natural disaster And sometimes just by natural selection
plant more bamboo for the pandas they wont adpated to other foods.Euther do that or force them to eat different foods.
