The Evolution of Marsupials and Related Bionic Applications——Taking Kangaroos as an Example

Abstract

As a typical marsupial, kangaroos have a unique reproductive structure, the pouch, which has great research and application value. Many studies have focused on the structure and function of kangaroo pouches and related applications. However, there are still controversies regarding evolutionary theory and so on. This article analyzes kangaroo pouches’ physiological characteristics, evolution, and application. It aims to delve into the characteristics and functions of this distinctive structure, exploring its unique structure and its pivotal role in developing kangaroo joeys. Additionally, it delves into the evolutionary origins of the pouch, dissecting the mechanisms potentially responsible for this extraordinary feature’s development. Understanding the evolutionary pathways behind the pouch not only sheds light on biodiversity’s shaping but also offers practical applications and insights, helping people have a new view of mother care and giving scholars inspiration for the reproduction of kangaroos, marsupial animals, and mammals.
