$\large\bf{\underline{\red{Morphological\:Evidence}}}$

Morphological Evidence is the data used to - 1) Detect and explain patterns of variation. 2) Define the limits of a species. 3) Determine evolutionary relationships. 4) Identify plant species.

Answer 2

Morphological evidence:

• based on the similarity of size, shape or structure of organs amont a group of organisms proving that they evolved from the same ancestor.

Anatomical evidence :

• evolution focuses on similarities and differences in the body structures of different species. ... Similarities in anatomical structures of different species signify that the two species have a relatively recent common ancestor.

Vestigial organs:

• Structures that have no apparent function and appear to be residual parts from a past ancestor are called vestigial structures.

Paleontological Evidence:

• Fossils are the geological remains and scientific traces of organisms in the past excavated from the soil. An example of paleontological evidence is the presence of rings on the surface of an oyster which represents the number of years of its life.

Connecting links:

• Figuratively, anything that links or joins one thing to another; that which serves to connect or unite members of a series, or to fill a hiatus between them: as, a connecting-link in an argument, or in a chain of evidence; a connecting-link between two orders of being.

embryological evidences:

• The study of one type of evidence of evolution is called embryology, the study of embryos. An embryo is an unborn (or unhatched) animal or human young in its earliest phases. Embryos of many different kinds of animals: mammals, birds, reptiles, fish, etc
