CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -When the genes are shared so it preserved the ancestor record where they share with each other and excludes the bacteria. And, if the DNA is the same for two organism so they would share the a common ancestor. hence, the last option is correct.

Detailed explanation-2: -In evolutionary biology, convergent evolution is defined as the process whereby distantly related organisms independently evolve similar traits to adapt to similar necessities.

Detailed explanation-3: -Examples of marsupial mammals include kangaroos, wallabies, wombats, the koala, and the Tasmanian devil. These three extant mammal groups-monotremes, marsupials, and placentals-are monophyletic, meaning the members of each group descend from one common evolutionary ancestor.

Detailed explanation-4: -If different species share common ancestors, we would expect organisms to share similarities inherited from those ancestors. Features inherited from common ancestors-even if their appearance is quite different in close relatives-are known as homologies.

Detailed explanation-5: -Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features). Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used to determine species’ relatedness.
