Species evolve over time based on their environment.
If part of a group of a species gets isolated into a new environment, then both species (the initial environment and the new one) will evolve differently because of their different environments and in result become different.
So since they both evolve differently based on their different surroundings, the group that was isolated becomes a new species.
The affinity of unrelated plants
to evolve superficially in similar characteristics under similar environmental
conditions like climates but separated by distance are influence by convergent
evolution. Seed dispersal has evolved independently in most plant
species. For instance, the fleshy part of a tomato is the walls of the outer
layer. This implies convergent evolution under selective pressure where competition
for seed dispersal is through consumption of fleshy fruits by animals such as
birds or ants.
Answer:
C. RNA
Explanation:
A primer of RNA is very much needed if someone is planning to go through the process of DNA replication.
They all have chromosome disorders (irregular number, extra or missing chromosomes)
