Question

The embryos of fish, tortoise, birds, and humans at some stage resemble closely. This is an example of __________ evidence of evolution.
A. Anatomical
B.Morphological
C. Embryological
D. Paleontological

Answer 1

Hint: The study that deals with the embryological structure and function of different animals are called embryology.

Complete answer: The study of positions of body parts and body organs is known as anatomy.
The study of the shape of an organism or a cell is known as the morphological study.
The study of fossils of plants and animals is known as a planetological study.
The study of embryological development is called embryology.

Additional information: Famous scientist Ernst Hackle said ‘ontogeny repeats phylogeny’ – means the development of an organism expresses evolutionary history related to all the intermediate forms of its ancestors.
1. This study was done based on the comparative study of the embryos of related groups of animals. The adult stages of every organism are different but morphologically the embryos show similarity in the early stages of life.
2. The embryos of fish, tortoise, birds, and humans show the presence of gill slits and tails in the embryo, maybe for some organisms, the tail gets vanished (for example frog) as development commence or tail become vestigial (example human) from the embryonic condition. This is evidence of embryological evolution.

So the correct answer is option C. Embryological.

Note: Evolution is an alternation in the heritable characteristics of biological populations over successive generations.
These characteristics are the expressions of genes that are moving on from parent to offspring during reproduction.
Different characteristics tend to exist within any given population as a cause of mutation, genetic recombination, and other forms of genetic variation
