Answer:
The correct answer is - punctuated equilibrium.
Explanation:
The phenomena represent punctuated equilibrium, according to which the new well-defined species appear suddenly and quickly. These species remain unchanged for a long time as they occur because of mutations in genes.
This phenomenon suggests that once it made in the fossil record the population becomes stable for a long time until they become extinct and have to adapt to the changes take place to survive.
Answer: Cell differentiation can be defined as a process in which the less specified cell is converted into the more specified cell. The cells at the embryonic stages is less specialized and during the process of development it becomes more specialized and this process is regulated by gene expression. The gene expression involves a specific group of genes which is expressed or suppressed, that decides the function of the cell.
A fertilized egg shows a single cell which is non-specialized that will become complex and will turn into a multicellular organism by cell differentiation.
This is the reason the adult rabbit looks so different from the single fertilized egg.
