Life on Lava
A Creation Reflection on a Recent Case of Microbial Succession
by Dr. Sarah Buckland-Reynolds
Volcanoes have long been heralded by evolutionists as one of the cradles of life’s origin due to the heat, minerals, and chemical energy that characterize those environments. The recent eruptions at Iceland’s Fagradalsfjall volcano (2021–2023) prompted scientists Hadland et al. from the University of Arizona to undertake a rare study of microbial primary succession in sterile lava. The study is framed within an evolutionary perspective, emphasizing its broader relevance, “given that volcanic terrains were potentially the first terrestrial habitats to harbor life on Earth and possibly other Earth-like planets such as Mars…” (Hadland et al, 2025).
Three eruptions at the Fagradalsfjall Volcano in Iceland show rapid and predictable microbial community establishment (Hadland et al., Nature Communications Biology 24 Nov 2025). The findings in this paper are hailed as a breakthrough in understanding ecosystem development. However, from a creation science perspective, it raises important questions about evolutionary assumptions and the design of life.
What the Study Found
Hadland et al.’s study tracked microbial colonization across three eruptions, creating what they called a “natural ecological triplicate.” Among their key observations were the following:
- Rapid Colonization
Hadland et al. reported that samples collected on the first day of the eruption already contained microbes, despite the fact that freshly ejected lava is known to be sterile due to the extreme conditions involved. As they noted:
“The chloroplast sequences appeared in samples as young as day 1… Amplicon sequence variants (ASVs) of genera known to include extremophiles were detected in day 1 to several weeks-old samples.”
Moreover,
“cell abundance in the basaltic lava increased as a function of lava age… a slope of 182 cells per gram of lava per day over the course of two years”.
The presence of microbes in day one samples challenges the evolutionary assumption that colonization requires long lag times. Udaeobacter and other extremophiles were detected almost immediately, showing that dispersal mechanisms are highly effective and that microbes are sufficiently resilient to survive immediate transfer to hostile substrates. These findings further demonstrate that microbial colonization is not slow or sporadic but steady and quantifiable. In the case of the Icelandic volcano, cell counts in some samples exceeded 200,000 cells per gram within just over two years.
While evolutionary expectations often emphasize gradual adaptation over long timescales, here we observe life establishing itself almost immediately in a sterile environment. In contrast, from an Intelligent Design perspective, this rapid colonization suggests that microbes are pre-equipped with survival mechanisms enabling them to thrive in extreme, nutrient-poor conditions. Their ability to quickly multiply on barren lava reflects foresight in design: that life is programmed to spread and fill niches efficiently, consistent with the biblical mandate in Genesis 1:28 to “fill the earth.”
- Microbial succession requires Earth-like conditions
Hadland et al.’s study further highlighted an important finding that presents a significant challenge to evolutionary explanations for the presence of life on other volcanically active planets. Initially, the authors explained that the microbes detected in the lava were primarily sourced from surrounding soils and aerosols. Later in the study, however, rainwater emerged as the dominant source, “…contributing up to 98% of the inferred source environments” (Hadland et al., 2025).
The role of earth system interconnectedness in volcanic colonization is highly relevant, since liquid water and non-sterile soil are features that distinguish Earth from other ‘Earth-like’ planets, such as Mars. In the Icelandic case study, Earth’s soil, atmosphere and hydrological cycle played crucial roles in microbial colonization. These external sources of microbes further undermine evolutionary claims of spontaneous generation in sterile environments. Instead, the evidence indicates that microbes were already present in the environment and dispersed into newly formed substrates, consistent with purposeful colonization.
From an Intelligent Design perspective, this finding reflects a finely tuned ecological web. Rain is not sterile but carries microbial life, ensuring that barren surfaces are rapidly seeded with organisms. This systemic interconnectedness points to design, highlighting once again that Earth’s systems are orchestrated to sustain and spread life.
The authors implicitly indicated that several of these results were unexpected, particularly the observation of a “…major shift in the sources of microorganisms, paralleling trends observed in taxa relative abundance, alpha diversity, and beta diversity.” The dominance of rainwater as a source was not anticipated, yet it consistently shaped microbial communities across multiple eruptions.
- Predictability
Another important finding reported by Hadland et al. was the remarkable predictability of microbial succession in the Icelandic case study. As the authors state:
“A random forest regression model trained on 2021 eruption data “accurately predicts the successional stage in the 2022 and 2023 eruptions” (Hadland et al., 2025).
The ability to predict microbial succession across eruptions indicates that colonization is not random but follows ordered, reproducible patterns. Evolutionary science often emphasizes chance and contingency, yet in this case a striking degree of law-like regularity is observed. From an Intelligent Design perspective, such regularity is expected, as predictability is a hallmark of design. If microbial succession were purely stochastic, predictive models would be expected to perform poorly. Instead, the fact that machine learning approaches could predict successional stages with high accuracy points to underlying order, reinforcing the view that life operates according to design principles.
Mars Comparisons: Why They Are Misleading
Hadland et al. partially framed the rationale for their study in terms of broader applications to other “Earth-like” planets, such as Mars, asserting that “volcanic terrains were potentially the first terrestrial habitats to harbor life on Earth and possibly other Earth-like planets such as Mars” (Hadland et al., 2025). On this basis, the researchers explicitly speculate that Martian volcanism could have produced transient habitats capable of supporting microbial life.
When the observations from the Icelandic case study are examined more closely, however, several significant limitations and flaws in this comparison become apparent, including:
- Water availability: In the Icelandic study, microbial sources were largely external to the lava. Rainwater in particular became the dominant source, accounting for up to 98% of inferred microbial inputs, with other sources, such as soils and atmospheric aerosols serving as important early contributors. However, liquid water is absent on Mars today and remains speculative even in its past.
- Atmosphere: As demonstrated in the Icelandic study, Earth’s atmosphere supports efficient microbial dispersal. By contrast, Mars’ thin CO₂ dominated atmosphere would far less conducive to such transport mechanisms.
- Radiation and temperature: Mars is exposed to intense surface radiation and extreme cold, conditions that would tend to sterilize exposed substrates and inhibit sustained microbial activity. This stands in sharp contrast to Earth’s comparatively protective atmosphere and temperate surface conditions.]
Therefore, when evaluated in light of the Icelandic evidence, the comparison to Mars appears to be ideological, resting more on presuppositional commitments than on direct empirical support. From an evolutionary starting point, the stated goal is to attempt to provide evidence of life’s proliferation beyond Earth; however, in this case, the primary data instead underscore the dependence of microbial colonization on Earth-specific environmental systems, thereby undermining that rationale rather than supporting it.
The Evidence Erupts Again
The Icelandic lava succession study is remarkable in that it inadvertently highlights the unique conditions Earth possesses to sustain the rapid proliferation of life. Nevertheless, the interpretation of these findings ultimately depends on one’s worldview. While evolutionary frameworks continue to extrapolate such results to Mars, the data themselves point instead to evidence of order, purpose and Earth-specific conditions that are difficult to generalize beyond our planet.
Notably, Scripture specifically identifies Earth as the place God created to be inhabited. As Isaiah 45:18 states:
“For thus says the LORD, who created the heavens, who formed the earth and made it; he established it; he did not create it in vain but formed it to be inhabited: I am the LORD, and there is no other.”
Ultimately, microbial succession on lava testifies to the Creator’s wisdom. Life is a gift, designed to flourish even under the harshest conditions. Mount Fagradalsfjall thus stands as yet another witness to God’s creation is resilient, purposeful, and continually renewed.
