Corvids are a family of birds that include crows, ravens, rooks, jackdaws, jays, magpies, and others. There are over 120 species of corvids worldwide, making them one of the most widespread and successful bird families. They are medium to large-sized birds, ranging from 11 inches to 2 feet in length, having stout and strong bills, which are slightly curved and shaped for omnivorous diets. Their feathers are iridescent black, brown, gray, or blue in coloration. Corvids are incredibly intelligent compared to other bird species. Their brains have a large forebrain where higher-order thinking occurs. Many corvids are highly social and live in family groups that work together to find food, defend territories, and rear young.

Supergenes are tightly linked clusters of genes that evolve reduced recombination, allowing sets of co-adapted traits to be inherited as single genetic units. They play an important role in maintaining complex polymorphisms across diverse organisms, from butterfly mimicry and social organization in ants to the evolution of human sex chromosomes.

Marine pharmacology is a branch of pharmaceutical sciences that deals with bioactive
compounds derived from marine organisms. These substances, found in the marine flora and
fauna, possess remarkable pharmacological properties that hold immense potential for modern
medicine.
