dvoudloných
Dvoudloných is a Czech term that translates to "diphyodont" in English, referring to mammals that possess two sets of teeth during their lifetime. This is in contrast to polyphyodonts, which have multiple sets of teeth, and monophyodonts, which only have one set. The first set of teeth, known as deciduous teeth or milk teeth, erupt during infancy and are later replaced by a permanent set of adult teeth. This developmental process is characteristic of most mammals, including humans. The transition from deciduous to permanent dentition is a crucial stage in an organism's life, enabling it to chew a wider variety of foods as it grows. The structure and number of teeth can vary significantly among different species, reflecting their dietary adaptations and evolutionary history. The concept of diphyodonty is a fundamental aspect of mammalian dental anatomy and evolution.
