What is ovulation?
Ovulation is the process in which a mature egg is released from the ovary. After it's released, the egg moves down the fallopian tube and stays there for 12 to 24 hours, where it can be fertilized.
Sperm can live inside the female reproductive tract as long as five days after sexual intercourse under the right conditions.
Your chance of getting pregnant is highest when live sperm are present in the fallopian tubes during ovulation.
In an average 28-day menstrual cycle, ovulation typically occurs about 14 days before the start of the next menstrual period.
However, each person's cycle length may be different, and the time between ovulation and the start of the next menstrual period may vary.

Genetic mutations, a sequence of nucleotides, and other information of DNA helps in the establishment of divergence from common ancestry. By comparing the information it gives an idea about the evolutionary ancestry of two or more species.
common descent means the evolutionary in biology and how they have something linked with their common ancestors.
