Hinduism is an Indian religion or dharma, a religious and universal order or way of life by which followers abide. As a religion, it is the world's third-largest, with over 1.2–1.35 billion followers, or 15–16% of the global population, known as Hindus. The word Hindu is an exonym, and while Hinduism has been called the oldest religion in the world, many practitioners refer to their religion as Sanātana Dharma, a modern usage, which refers to the idea that its origins lie beyond human history, as revealed in the Hindu texts. Another endonym is Vaidika dharma, the dharma related to the Vedas.

Sex is the trait that determines whether a sexually reproducing animal or plant produces male or female gametes. Male plants and animals produce smaller mobile gametes, while females produce larger ones. Organisms that produce both types of gametes are called hermaphrodites. During sexual reproduction, male and female gametes fuse to form zygotes, which develop into offspring that inherit traits from each parent.

Islam is an Abrahamic monotheistic religion centred primarily around the Quran, a religious text considered by Muslims to be the direct word of God as it was revealed to Muhammad, the main and final Islamic prophet. It is the world's second-largest religion behind Christianity, with its followers ranging between 1-1.8 billion globally, or around a quarter of the world's population. Due to the average younger age and higher fertility rate, Islam is the world's fastest growing major religious group, and is projected by Pew Research Center to be the world's largest religion by the end of the 21st century, surpassing Christianity. It teaches that God is merciful, all-powerful, and unique, and has guided humanity through various prophets, revealed scriptures, and natural signs, with the Quran serving as the final and universal revelation and Muhammad serving as the "Seal of the Prophets". The teachings and practices of Muhammad documented in traditional collected accounts provide a secondary constitutional model for Muslims to follow after the Quran.
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from 8.5 micrometres (0.00033 in) to 33.6 metres (110 ft). They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology.
