1) The Importance of Darwin’s Theory: Darwin’s major development theories aimed to prove that life emerged, deviating from lower to higher forms. With the passage of time, this evolutionary process became more complex, causing better-adapted individuals to exist. Animals and plant species inhabiting the Earth are subject to change, and it is through these changes that new forms of development originate.
2) Evolution: The process of continuous change over

It’s crucial to distinguish between the ‘source of law’ and the ‘source of legal norms,’ which refers to those who wield the power to create legal norms and the manner in which these rules are expressed. We differentiate between formal and material sources.
