Intellectual manifested reality of 24/7 is estimated time tomorrow arrives midnight to noon
estimating time alive(ETA so far using relative time theory).
Each instinctive brain living since conceived evolving between stages of development every ancestor that lived or alive goes through daily regardless male or female zygote, embryo, fetus, infant, toddler, adolescent, puberty, teen, adulthood(capable of reproduction), parenting a next generation or not, becoming a grandparent when children become parents, becoming a great grandparent with grandchildren become parents, etc.
All done in series parallel positions of ancestry occupying time daily here. Actual time evolving(ATE)
How does one graph that into proportion that can range from less than a century 5 generation gaps were added so far to 170 years depending on when great great grandchildren become parents.
5 parallel vertical axses to one horizontal plane of middle of 5 generation gaps living daily here, 4 grandparents. 16, 8, 4, 2, each great great grandchild changing population never same forms since a fertilize cell added.
male or female two halves of a next generation of male or female offspring per son or daughter added by a mom and dad.

.
This is established ancestries so far. Actual time evolved every generation since inception of the species and 5 ancestral lineages with 5 generation gaps in one scale larger than the 7 degrees of separation by ETA. humanity's relative time theory of Estimated Tomorrows Alive. 7 days a week 52 weeks every year after birth until dead.
