What feature of embryology makes it capable of providing data for common evolutionary history not readily available from other sources

The Group of choices associated with the question is as follows:

A) As the embryo develops, it reveals the expression of genes.

B) The growth of the embryo is achieved by the differentiation of cells.

C) A developing embryo exhibits structures not present in the adult animal.

D) The development of embryos of a certain species is consistent

The correct answer is - C) A developing embryo exhibits structures not present in the adult animal.

Explanation:

The study of the development of anatomy to the adult form of an organism is embryology that helps in giving an idea about the evolutionary development and considered as embryological evidence which lost after developing into adult such as analogous structures.

Embryos are the structure that conserves the development pattern of widely divergent groups of organisms and therefore, used as evidence of evolutionary development.

americans began to notice growing differences between the northern and southern sections of the country. there were more people living in cities in the north, which made it more urban. more people lived on farms in the south, which made it more rural. while many people were farmers in the northern states, there were now other ways to make a living, such as working in mechanical cotton gins factories manufacturing cloth, tools and other goods. people in the north supported high tariffs on goods imported from europe because the extra cost encouraged people to “buy american” instead. in the southern states, planters did not like tariffs because they sold most of their production to europe and bought their tools from there as well. southerners believed the protective tariff was something that only northern factory owners keep their profits high. so the southern politicians came up with an idea. they would opt out. they would simply ignore the protective tariff. it was ‘null and void’ in south carolina. the state would not collect the taxes on goods imported into south carolina, no matter what the president said they had to do. this decision led to the nullification crisis.
