The eastern Canadian bacterial strain is still evolving, but eastern Canadian birds are no longer evolving.

1. True
2. False

Answer :

Final answer:

Evolution continues in all organisms, including the eastern Canadian bacterial strain and birds. It is driven by natural selection, gene flow, genetic drift, and mutation, and doesn't cease over time or with changes in the heterozygote frequency.

Explanation:

The statement 'The eastern Canadian bacterial strain is still evolving, but eastern Canadian birds are no longer evolving' could be viewed as inaccurate or oversimplified. Evolution, defined as changes in gene frequencies in populations over time, is a continuous process that constantly occurs in all living organisms, including both prokaryotes like bacteria and eukaryotes like birds. The rate of evolution might vary depending on a variety of factors such as the speed of mutation, gene flow, genetic drift, natural selection, etc.

So, the Canadian bacterial strain and the Canadian birds, being part of the biosphere, are likely subject to these evolutionary forces and hence, they are still evolving. However, it is virtually impossible to categorically state whether a given bacteria or bird has stopped evolving without ample scientific evidence.

A key point to remember is that evolution doesn't cease because time has passed or the heterozygote frequency has changed as suggested by some of the reference information provided. Rather, it is driven by the laws of natural selection and the influences of gene flow, genetic drift, and mutation. Hence, unless external forces (like the laws of physics governing migratory patterns or use of antibiotics leading to drug resistance in bacteria) halt these influences, evolution continues for both the bacteria and the birds.
