What does the presence of homologous structures in different organisms suggest? a.) similar movement b.) common ancestry c.) similar habitat d.) common distribution

The correct answer is option B. common ancestry.

Explanation:

Organs with different functions but with a similar structure, such organs are homologous organs.  An organ that appears in various animals, underlining anatomical similarities which explains that they share a common ancestry.

When very different organisms have a skeleton or having homologous organs that appear very similar anatomically and seem to be connected or having common ancestors. Such as human arm, dolphin fins, bat wings, and others.

Thus, the correct answer is option c.

in situ hybridization has been widely used for research applications, including clinical cytogenetics, gene mapping, tumor biology and studies of chromosome evolution.
