Hairless mammals have genetic changes in both their protein-coding and regulatory sequences related to hair.

Hairless mammals evolved quickly in both gene and non-gene areas related to skin and hair.

The research suggests that the global distribution of PCOS is likely due to historical human migration and that genes affecting PCOS may have different impacts on males and females.

The document concludes that understanding health requires considering evolutionary perspectives on reproductive fitness, and recognizing the complexity of factors like diet, testosterone, and sexual orientation.

The conclusion suggests that PCOS may persist due to genetic traits that, while harmful for female fertility, could have provided survival and reproductive benefits to males.

Understanding where cancer cells come from helps create better prevention and treatment methods.

Humans lost body hair relatively recently in evolution.

The research found how GPCR Class A Rhodopsin receptors are related and suggested possible substances they interact with.

Changes in the HR gene have influenced hair growth and may lead to hair loss conditions in humans.

Sardinians were historically short due to a mix of genetics and factors like disease and poor nutrition, but recent height increases suggest better living conditions had a bigger impact.

Cetaceans lost hair due to changes in the Hr and FGF5 genes.

Sheep and goat hair fibers are complex due to keratin-associated proteins, which are important for fiber properties and growth.

Human hair loss may have evolved to help increase brain size.

Different hair types in mammals are linked to variations in specific protein genes, with changes influenced by their living environments.

New CRISPR/Cas9 variants and nanotechnology-based delivery methods are improving cancer treatment, but choosing the best variant and overcoming certain limitations remain challenges.

Modern lifestyles, including poor diet, stress, and long-term use of certain medications, hinder the body's ability to heal from inflammation, leading to chronic diseases.
