Answer 2

It is very difficult to answer this question for a number of reasons. First, it is very hard to pinpoint the exact time when an animal becomes extinct. Sometimes the species exists in the wild in a remote area and it is difficult to spot. It is difficult to know whether they cannot be found because they are extinct or because they are difficult to spot or distinguish from similar species. Some species have not been declared extinct when they probably are, and others are declared to be extinct and then afterward an example of the species will be found. Almost all declarations of extinction are guesses to a certain extent.

Be that as it may, there are an extraordinary number of species which have disappeared in the last two centuries. Wikipedia lists over 200 birds alone. The number of mammals, fish, molluscs and other creatures must swell this number to over 1000

Answer 3

Every day from 35-150 species become extinct so you can now calculate with average value of 93 per day * 365 per year and multiply by 110 years and you get enormous number of 3,733,950 species become extinct since 1900!

Answer 4
