what is Similar structures that related species have inherited from a common ancestor
Some structures that related species have inherited from a common ancestor are homologous structures, which are similar in form and function but may have different appearances due to adaptations to different environments. Another example is vestigial structures, which are remnants of structures that were functional in ancestral species but have reduced or lost their original function in descendants. Analogous structures are also seen in related species, having similar functions but different origins, such as the wings of birds and insects.
The structures of macro-molecules, such as DNA and proteins, can be used to infer relatedness between species because they are inherited from common ancestors. By comparing the similarities and differences in the sequences of these molecules among different species, scientists can construct phylogenetic trees that show the evolutionary relationships between them. Closer related species tend to have more similar macro-molecular structures than distantly related species.
yes
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. hope it helped
