Answer:
Phylogenetic trees can be described as diagrams which represents the evolutionary histories of organisms. The organisms that share more common traits or functions are more closer to one another in the diagram.
The phylogenetic tree in the above diagram shows that the ancestors of Danes, Chinese and Tibetans carried the regular EPAS1 alleles.
According to the tree, the Chinese are more closer to the Tibetans as they carry the Tibetan EPAS1 alleles which the Danes do not carry.
When a population is
small in a habitat, its population growth is exponential. This means it doubles
its population with every generation. This is because there is plenty of resources
and little competition between individuals of the population. However, as the population
grows bigger, the population reaches carrying
capacity (the maximum number that the ecosystem can hold). The growth slows and
stagnates as stiff competition results to an equal death rate as birth rate.
I'm thinking it might be fossil evidence. Hope it helps!
A skeptical scientist is one who questions the reliability of certain kinds of claims by systematically investigating them. it is an important quality in a Scientist because it helps them remain objective when performing scientific injury and research, it also forces them to examine claims to be certain that there is sufficient evidence to back them up
