If the population/number of the things they need decrease, so will the number of the organism
The other events that most likely occurred during the same time period would be; An environmental change that did not favor the individuals in the population with the allele most likely led to the change in allele frequency; because the allele frequency decreased by so much, there would had to have been a decrease in the population within a three generation period of time.

Some species look similar because they evolved in similar environments. Similar environments impose similar challenges, and traits improving survival are favoured. These organisms would not be closely related, however, because they evolved from different species and different regions. This is known as convergent evolution.
Bacteria can evolve quickly because they reproduce at a fast rate. Mutations of bacteria produce new strains. Some bacteria might become resistant to certain antibiotics.
