Evolutionary psychology works backward to propose an explanation; thus, any behavior can be explained Evolutionary psychologists have suggested that women prefer monogamy and men promiscuity in ensuring the survival of their genetic material. However, monogamous relationships can also be explained using an evolutionary perspective.

WebJun 7, 2024 · Epigenetics is the study of changes in gene activity that can be transmitted through cell divisions but cannot be explained by changes in the DNA sequence. Epigenetic mechanisms are central to gene regulation, phenotypic plasticity, development and the preservation of genome integrity. WebBecause epigenetic selection removes particular DNAm vari-ants from the population, it may change the distribution of DNAm in survivors. Thus, it should be possible to detect signa-tures of epigenetic selection in utero from DNAm data in human populations (similarly to the rationale for detecting signatures of selection in DNA sequence data).
WebEpigenetic variation within multicellular organisms is either endogenous or exogenous. [10] Endogenous is generated by cell–cell signaling (e.g. during cell differentiation early in development), while exogenous is a cellular response to environmental cues.
