When a lineage splits into multiple line of descents, then, it leads to speciation. It is a process by which a single population evolves into different species. The process of speciation leads to the development of two or more species as the lineages are splitted. These two evolved species are genetically independent.
Hence, the blank can be filled with 'speciation'.
The answer for this question is C, I just did my final for Biology and got a good score in it.
Hope it helps!

Answer & Explanation:
( Rh Factor ) represents the presence of the Rhesus protein in the blood.
( Rh+ ) blood contains the rhesus protein.
( Rh- ) blood does not contain the rhesus protein.
( Type O ) blood is the universal donor.
( Type AB ) blood is the universal recipient.
( Rh+ ) blood can receive Rh+ or Rh- blood.
( Rh- ) blood can receive Rh- blood.

Answer:
5556
Explanation:
If a DNA polymerase synthesizes in average 50 nucleotides/second, that means that in three hours (10800 seconds) it synthesizes about 540000 nucleotides.
However, if the human genome is composed of 3000000000 (3 billion) base pairs (nucleotids), the minimum number of DNA polymerases (working in the same number of origins of replication) to finish the duplication of all the genome in three hours is 5555,5. (3000000000/540000). As we know there is no half polymerase, so we round to 5556.
5556 molecules of DNA polymerases acting on 5556 origins of replication are needed.
