Hypothesis
Ontogenetic features of living organisms can be considered biomarkers of coevolution between organisms and physicochemical agents during Earth’s history.
Conclusion
The study suggests that developmental features of organisms reflect environmental changes throughout evolution.
Supporting Evidence
- Early multicellular life forms likely existed in an anoxic Earth over 2 billion years ago.
- Amphibian embryos show significant changes in oxygen requirements as they develop.
- Stage-dependent susceptibility to environmental stressors reflects evolutionary history.
Takeaway
This study looks at how the way living things grow can show us how they adapted to changes in the environment over a long time.
Potential Biases
Sampling and preservation of fossils may lead to an incomplete understanding of biodiversity evolution.
Limitations
The fossil record may bias our understanding of evolution due to difficulties in recognizing ancient biotic tissue.
