Give definitions for comparative anatomy and embryology. Why do evolutionary biologists seek data from multiple lines of evidence to support evolution as a theory? Solution Ans.) Comparative anatomy is the study of similarities and differences in the anatomy of diverse species. It has quite a long served as confirmation for development; it demonstrates that different organisms share a typical progenitor. Likewise, it helps researchers to group the living organisms with their comparative qualities on the basis of anatomical structures. A typical case of comparative anatomy is the comparable bone structures in forelimbs of felines, whales, bats, and human. These members comprise of similar essential parts; yet, they serve totally unique capacities. The skeletal parts which shape a structure utilized for swimming, for example, a balance, would not be perfect to frame a wing, which is more qualified for flight. One clarification for the forelimbs\' comparative structure is plummet with alteration. Through arbitrary transformations and characteristic choice, every life form\'s anatomical structures bit by bit adjusted to suit their particular natural surroundings. Embryology is the study that reviews the pre-birth advancement of embryo, gametes and improvement of developing lives and babies.

Evolutionary biologists seek data from multiple lines of evidence because they need all the support to prove their evolution theory. The research on comparative anatomy and embryology of particular organism gives insight about their evolution; that how they evolved and forms a different organism, Hence, multiple lines of evidence are required to support the new findings.

Why do evolutionary biologists seek data from multiple lines of evidence to support evolution as
a theory?
Solution
Ans.) Comparative anatomy is the study of similarities and differences in the anatomy of diverse
species. It has quite a long served as confirmation for development; it demonstrates that different
organisms share a typical progenitor. Likewise, it helps researchers to group the living organisms
with their comparative qualities on the basis of anatomical structures. A typical case of
comparative anatomy is the comparable bone structures in forelimbs of felines, whales, bats, and
human. These members comprise of similar essential parts; yet, they serve totally unique
capacities. The skeletal parts which shape a structure utilized for swimming, for example, a
balance, would not be perfect to frame a wing, which is more qualified for flight. One
clarification for the forelimbs' comparative structure is plummet with alteration. Through
arbitrary transformations and characteristic choice, every life form's anatomical structures bit by
bit adjusted to suit their particular natural surroundings.
Embryology is the study that reviews the pre-birth advancement of embryo, gametes and
improvement of developing lives and babies. Also, embryology includes the analysis of genetic
characters also which took place before birth of the progeny; this phenomenon is known as
teratology.
Evolutionary biologists seek data from multiple lines of evidence because they need all the
support to prove their evolution theory. The research on comparative anatomy and embryology
of particular organism gives insight about their evolution; that how they evolved and forms a
different organism, Hence, multiple lines of evidence are required to support the new findings.
The new research is completely based on such kind of studies.
