Men Are Willing to Adopt Children: Against Darwinian Fitness
According to the report from National Survey of Family Growth, men are more willing to adopt children compared to women. American men ages between 18- 44 are more than two times as likely as women in the same age group to have adopted a child. It showed that more than 1.2 million men and 613,000 women had adopted children. The reason for this difference could be partly due to men getting married and adopting their spouse’s children from a previous relationships. We all are designed to pass our gene to next generation, but this is a threat to our survival and fitness.
Genome Changes With Age
Human genomes can change throughout a person’s lifespan. It’s influenced by environmental or nutritional factors. This change may explain the reasons for different deadly illnesses such as cancer which comes with age. Researchers at Johns Hopkins University found epigenetic marks on a DNA sequence which modify over the course of one’s life. The extent of such changes is similar among family members. The changes in the genomic structure can occur as a result of dietary and other environmental exposure. Epigenetics may play a role in diseases like diabetes, autism and cancer.

It’s been suggested that symmetrical faces are indicators of a good “mate” , and these mates have good genes which can be inherited by the next generation.
Inflammatory Arthritis Gene Links to Heart Risks
Gene that related to inflammatory arthritis called HLA-DRB1 is associated with heart diseases. British study finds that this gene increases the chances of premature death from cardiovascular disease (CVD). People with rheumatoid arthritis tend to die younger, and largely from CVD.
