Is the resemblance between timber wolves and tasmanian wolves the result of common ancestry

Yes

Explanation:

Homologous structures or similar structural features can be a result of common ancestry. DNA comparison and analysis between the species can be used to identify the common ancestor.

humans, along with other animals and plants, have linear chromosomes that are arranged in pairs within the nucleus of the cell. the only human cells that do not contain pairs of chromosomes are reproductive cells, or gametes, which carry just one copy of each chromosome.

desert perennials often survive by remaining dormant during dry periods of the year, then springing to life when water becomes available. most annual desert plants germinate only after heavy seasonal rain, then complete their reproductive cycle very quickly.
