Discuss the evolution of life from a single mother cell to multicellular life form

Explanation:

How did life become multicellular?

In the history of life, multicellular organisms have independently originated at least 25 times from unicellular ancestors [1]. ... Multicellular clusters can emerge either as the result of clonal development (staying together in terms of [10]) or by aggregation of cells and smaller clusters (coming together).

a time line cause it goes from 685 to 978

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."
