CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. These structures may or may not have the same function in the descendants. Figure below shows the hands of several different mammals. They all have the same basic pattern of bones.

Detailed explanation-2: -Multiple types of evidence support the theory of evolution: Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features).

Detailed explanation-3: -A common example of homologous structures in evolutionary biology are the wings of bats and the arms of primates. Although these two structures do not look similar or have the same function, genetically, they come from the same structure of the last common ancestor.

Detailed explanation-4: -Structures with similar anatomy, morphology, embryology and genetics but dissimilar functions are known as homologous structures. Structures that are superficially similar but anatomical dissimilar doing the same function are known as analogous structures.

Detailed explanation-5: -Homologous structures indicate that the species came from a common ancestor and are related through evolution. When two different species have the same bone structure, it indicates that they once had a common ancestor.
