It is assumed that organisms with similar anatomical characteristics have evolved relatively recently and have a common ancestor.
<h3>How does comparing the physical characteristics of different creatures help us understand evolution?</h3>
To comprehend how living things originated, scientists study the anatomy, embryos, and DNA of various species. Homological structures provide proof of evolution. These are features that were passed down from a common ancestor and are shared by related creatures. An further piece of evidence for evolution is offered by similar structures.
<h3>What role does anatomy play in the study of relationships between various types of organisms?</h3>
Comparative anatomy, which compares structural similarities, is one of the strongest types of evidence of creatures to ascertain the links between them throughout evolution. It is assumed that organisms with similar anatomical traits have evolved from ancestors who were reasonably closely connected to one another.

In exponential growth, the growth rate of population per capita remains the same in spite of the size of the population, thus, resulting in the population to grow faster and faster as it gets bigger. However, in nature, the populations may grow exponentially for certain time duration, and they eventually get restricted due to limited availability of resources.
In the graph, it is evident that from 1950 to 1990 there is exponential growth, signifying that the fish exhibited almost optimal conditions of living. However, in 1990 the population started to decline steadily, demonstrating an extreme lack of resources or enhancement in predatory species.
<u>ANSWER:</u>
'Adaptations enhance survival' is true about all adaptions.
<u>EXPLANATION:</u>
- Adaptation is a mechanism in organisms that allows them to adjust with the changes in their current environment or to adapt to their new environment.
- Darwin explained this as a concept of a natural selection process where organisms are susceptible to the variations with the environmental changes.
- These variations which are associated with greater survival and reproductive success are retained in the progeny. This phenomenon is known as Darwinian fitness.
