Answer:
Possession of inherited adaptations that maximize fitness.
Explanation:
Basically ones that are best adapted for their environment. (I'm assuming "he" is Darwin?)
Most mutations have no effect on organisms. Organisms all have large amounts of genetic code, most of which has no effect. As a result, mutation of this code is rarely meaningful.

It is part of the central nervous system (CNS) along with the brain. It is divided into different segments. Each segment contains a pair roots made out of nerve fibres.

Answer:
A cladogram is a diagram used to represent a hypothetical relationship between groups of animals, called a phylogeny. A cladogram is used by a scientist studying phylogenetic systematics to visualize the groups of organisms being compared, how they are related, and their most common ancestors. A cladogram can be simple, comparing only two or three groups of organisms, or it can be enormously complex and contain all the known forms of life.
Cladogram design is universal, although simple. A cladogram consists of the organisms being studied, lines, and nodes where those lines cross. The lines represent evolutionary time, or a series of organisms that lead to the population it connects to. Nodes represent common ancestors between species. At some point in the past a population of common ancestor organisms was divided, giving rise to the different organisms being studied. Some cladograms show evolutionary time through the scale of the lines, longer lines meaning more time. Some cladograms chose to show extinct species, while others omit them. Any particular cladogram is formulated specifically for the use it is needed.
