Changing gravity level and the development of animals

Area of Science:

• Space Biology
• Gravitational Biology
• Evolutionary Biology

Background:

• Extensive data exists on microgravity's effects across biological organization levels (microorganisms to humans).
• Research in hypergravity also exists, but comparisons often focus on body mass, not biological organization.
• Current research lacks a systematic comparative biological analysis of responses to altered gravity.

Purpose of the Study:

• To address the lack of comparative analysis in space and hypergravity research.
• To propose a framework for analyzing biological responses based on evolutionary resistance and reactivity.

Main Methods:

• Conceptual analysis based on N.N. Sirotinin's (1981) theory of evolution of resistance and reactivity.
• Review of existing space biology and hypergravity research data.
• Identification of gaps in comparative biological analysis.

Main Results:

• Current research often selects biological models randomly, hindering comparative analysis.
• A comparative biological approach is needed to understand gravity's influence across different life forms.
• The study raises the problem of inconsistent methodologies in gravitational biology research.

Conclusions:

• A systematic, comparative approach is crucial for advancing space and gravitational biology.
• Applying evolutionary concepts of resistance and reactivity can provide a unified framework for research.
• Further research is needed to develop and implement comparative analyses in this field.
