I found the exercise on the internet and these were the options:
"A)Did this girl grow up in a single-parent mother-headed family?
B)Was this girl insecurely attached?
C)Did this girl have a stressful childhood?
D)<span>Does this girl have many siblings?"
Correct answer: D
The number of siblings is not a factor that promotes early puberty in girls. All the other factors do have an impact although the mechanisms are yet not very well known. When there is not a father figure present, girls tend to reach puberty earlier. When they are insecurely attached to their mother, girls also tend to reach puberty earlier. Lastly, another factor that may lead to an earlier puberty in girls is the stress they've passed through during childhood - mostly from family conflicts, whether with parents or siblings.</span>

Answer:
option c punctuated equilibrium
Explanation:
Punctuated equilibrium occurs in a process whereby evolutionary changes occurs in some organisms in a rapid burst of time rather the conceived gradual changes that occurs over a long period of time. this burst of time might be in about 500,000 years. It is assumed that the organism has maintained/lives in stasis for a long period without a need for change, but then, once the change takes place (most of the time, due to an environmental factor), the organism quickly adapts to its new environment with this new adaptation.
