at 3 months gestation
Fingerprints start to form around the 13th week of gestation in the womb, with the ridges fully developed by the sixth month of pregnancy. By the time a human is born, they already have their unique set of fingerprints.

there were no humans in the ice ageNonsense, stone age modern humans lived on all the continents except antarctica and south America in the last ice age. It is hard to be certain of average height, that varies both with inheritance and diet.
Cro-magnon or homo sapiens sapiens. By the end of the last ice age, we had evolved (as best we can tell) into the form we currently have.
The three eras early humans have lived into are the Paleolithic Era (Old Stone Age), the Mesolithic Era (Middle Stone Age), and the Neolithic Era (New Stone Age). These eras mark significant developments in human history, including the use of tools, agriculture, and settled communities.
Fingerprints begin to form during the third trimester of pregnancy and remain constant throughout a person's life. Therefore, individuals of any age will have fingerprints.

Humans typically begin to shrink in height around the age of 40, with the rate of shrinking increasing as they get older. This shrinking is primarily due to age-related changes in the spinal discs and vertebral bones.
Fingerprints can be lost, although I'm not sure if old age will do it. My mother lost her fingerprints because she has worked in secretarial-type jobs all her life. The paper wore down the prints after years.
in the first trimester/3 MONTHS
I believe that fetal fingerprints are fully formed by 12 weeks/3months of gestation. Fingerprints are actually created by fetal movements - as the young fetus moves within the uterus, its skin shifts, forming the ridges of its fingerprints. This is the reason why no two people have the same fingerprints, even identical twins.
In a study on inherited fingerprint patterns, a constant might be the age of the individuals studied, as age can impact the clarity and definition of fingerprints. By keeping age consistent, researchers can isolate the genetic factors influencing fingerprint patterns.
Fingerprints do not fade with age on a natural basis. However, they can be altered over time due to skin conditions, injuries, or external factors. Generally, fingerprints remain stable throughout a person's lifetime.
At what age did female slaves begin to have children.
Humans start learning from the moment they are born, with basic skills like language acquisition, motor skills development, and social interactions. Learning continues throughout life as individuals acquire new knowledge and skills through experiences, education, and interactions with their environment.
Cats can begin breeding as early as 4 to 6 months of age.
