According to the passage, natural selection cannot anticipate future environments on the earth as<br/>1. species not fully prepared to face the environmental changes that await them will face extinction<br/>2. all the existing species would get extinct as their genomes will not withstand biological mishaps<br/>3. inability of the genome to withstand environmental changes would result in extinction<br/>4. extinction of species is a common feature<br/><br/>Select the correct answer using the code given below.

1. Correct. If species are not adapted to future environmental changes, natural selection cannot pre-equip them; such species may go extinct.

2. Incorrect. The passage idea is not that all existing species will go extinct due to genomes failing against biological mishaps; this is too absolute and not implied.

3. Correct. If genomes cannot cope with environmental change, extinction can result; natural selection works only on present variation, not future needs.

4. Correct. Extinction is a common feature in evolutionary history, which supports why natural selection cannot guarantee survival in future environments.

Hence, the correct set is 1, 3 and 4.
