frez [133]

Answer:

Study of comparative anatomy emerged in the 18th century and led to establishment of relationship between species based on the common traits

Explanation:

The three major events that occurred after this discovery are –  

a) Discovery of the fact that the age of earth is much higher than the age of earth as found in previous theories of continental drift theory

b) The age of the oldest fossils was determined and based on that relative age of all species (as found in fossils) was determined.  

c) The determination of age of fossil helped to find the gaps in the evolutionary tree and hence provoked search of these missing species.

The study of comparative anatomy started somewhere around 1800 when George Cuvier emerged as father of comparative anatomy

Based on comparative anatomy study, scientists such as Buffon and Lamarck worked on establishing relationship between species based on the common traits shared between them

There is the famous example of a butterfly’s flapping wings influencing the weather thousands of miles away.

it can be applied to ecosystems. Empirical dynamic modeling, which is based on chaos theory, uses sea surface temperature to help predict salmon population fluctuations.
