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.
Answer: The “leaf like” stalk that emerges is Sporophyte.
Individuals adapt to their environments and, thereby, evolve
Explanation:
Natural selection is the main process which advances evolution by aiding organisms to survive and produce more offspring through adapting more to their environment. Mutations, gene transfer, and genetic variations also drive evolution.
Both natural selection and evolution work on genetic behaviors in populations rather than individuals. Both natural selection and evolution are involved in generating changes over generations. Examples of evolution is the disappearing of tail bone, decreased head size and for natural selection example is the long and short necked giraffe.
