Question

define the fossil extinet species with ex. ​

Answer 1

Answer:

When a species disappears, biologists say that the species has become extinct. By making room for new species, extinction helps drive the evolution of life. Over long periods of time, the number of species becoming extinct can remain fairly constant, meaning that an average number of species go extinct each year, century, or millennium. However, during the history of life on Earth, there have been periods of mass extinction, when large percentages of the planet’s species became extinct in a relatively short amount of time. These extinctions have had widely different causes.
