Question

Почему же организмы не обзаводились скелетом до начала скелетной революции?

Answer 1

Потому что они не нуждались в скелете вследствие того, что жили в воде.

Answer 2

Я считаю потому что значит организмы в этом не нуждались. Ведь эволюция происходит только если без это нельзя выжить.

Answer 3

Why didn't organisms develop skeletons before the skeletal revolution?

The development of skeletons in organisms was a complex process that took millions of years to evolve. Prior to the skeletal revolution, organisms did not have the structural support provided by skeletons. Here are some possible reasons why organisms did not develop skeletons before the skeletal revolution:

1. Evolutionary constraints: The evolution of complex structures like skeletons requires a series of genetic mutations and adaptations over long periods of time. It is possible that the necessary genetic mutations for developing skeletons did not occur until later in evolutionary history.

2. Environmental factors: The absence of skeletons in early organisms may have been influenced by environmental factors. For example, in aquatic environments, buoyancy provided by water may have reduced the need for skeletal support. Additionally, the absence of predators or other environmental pressures may have made skeletons unnecessary for survival.

3. Functional trade-offs: Organisms without skeletons may have had other adaptations that provided advantages in their specific environments. For example, soft-bodied organisms may have been more flexible and able to navigate through narrow spaces or burrow into substrates more easily than organisms with rigid skeletons.

4. Energy efficiency: Developing and maintaining a skeleton requires energy. Organisms without skeletons may have been able to allocate their energy towards other important functions, such as reproduction or growth, which provided a greater evolutionary advantage at the time.

It is important to note that the exact reasons for the absence of skeletons in early organisms are still the subject of scientific research and debate. The factors mentioned above are some possible explanations, but further studies and discoveries may provide additional insights into this topic.
