How have organisms adapted to their changing environment from the precambrian time to the Cenozoic era?

Answer 1

Organisms have adapted to their changing environments from the Precambrian to the Cenozoic era through various evolutionary processes such as natural selection, genetic mutations, and the development of new traits. For instance, early multicellular organisms evolved in response to increasing oxygen levels, leading to more complex life forms. During the Mesozoic era, adaptations such as warm-bloodedness in dinosaurs and flowering plants emerged to exploit new ecological niches. In the Cenozoic, mammals and birds diversified, developing traits like fur, feathers, and specialized feeding mechanisms to thrive in diverse habitats shaped by climatic changes.
