How does our knowledge of microbial evolution give us a better understanding of the threats posed by avian influenza?

Explanation:

Evolution which is a process as described by Charles Darwin who propose the theory of evolution as the gradual development of species from simple to complex forms .

Microbial evolution refers to the changes that occur in microorganisms and that are retained over time, and this change could be genetical.

Avian influenza viruses which is one of the global virus with new antigenic subtypes caused death of many people.aquatic birds are also the source of all these influenza viruses in some animal species.The transmission of influenza virus can be from birds in live poultry to humans. Avian influenza viruses can also be transmitted to animals like horses, and mammals. because of the viral replication in it's hosts there isbelive that avian influenza viruses are not transmitted directly to humans in nature.

Therefore since this avian influences is most often contracted by sick birds which can also be can also be passed from person to person, then evolution helps us to know that it moves from simple to complex species.

enhanced global partnerships and exploration capabilities may advance international preparedness for protecting the earth from catastrophic events such as some asteroid strikes, advancing collaborative research on space weather and protecting spacecraft by developing new means for space debris removal.
