Ans 1: Main stages associated with
transitions
- Group formation: Group formation is
associated with developmental activities and increase in
functionality of an organism.
- Emergence of reproductive altruism
among group: The reproductive altruism and individuality is
produced in the larger members of the volvocine group.
- Cell specialization: The
specialization in the group of cells is necessary so as to perform
specific perform a special function. Eg parietal cell
development.
Ans 2: The understanding between
genotype and phenotype is necessary in order to understand evolving
system. The identification of logical functions is necessary to
evaluate complex functions. The total count of novel phenotypes
which can reach by genotypic change is greatest for organisms with
simple phenotypes.
