  journal={arXiv: Astrophysics},
We review the thermal history of the Universe. We obtain a new estimate for the thermal history of the Earth over the past four billion years using a biological thermometer based on (1) a rough estimate of the absolute time calibration of the genetic distances in the 16S rRNA-based tree of terrestrial life and (2) the maximum growth temperatures of the extant organisms used to construct the tree. The only other thermometer on comparable time scales is based on a controversial interpretation of… Expand
The Habitability of Our Earth and Other Earths: Astrophysical, Geochemical, Geophysical, and Biological Limits on Planet Habitability
For life-forms like us, the most important feature of Earth is its habitability. Understanding habitability and using that knowledge to locate the nearest habitable planet may be crucial for ourExpand
Biospheric Evolution Is Coarsely Deterministic
Starting with the origin of life, I argue that the general pattern of the tightly coupled evolution of biota and climate on Earth has been the very probable outcome from a relatively small number ofExpand
Metabolic and taxonomic diversification in continental magmatic hydrothermal systems 4 . 1
Hydrothermal systems integrate geological processes from the deep crust to the Earth’s surface yielding an extensive array of spring types with an extraordinary diversity of geochemical compositions.Expand
What Can Life on Earth Tell Us About Life in the Universe
We review the most fundamental features common to all terrestrial life. We argue that the ubiquity of these features makes them the best candidates for being features of extraterrestrial life. OtherExpand
16 Temperature, Biogenesis, and Biospheric Self-Organization
It is argued that the biosphere has evolved deterministically as a selforganized system, given the initial conditions of the Sun-Earth system, and that emergence of life and its major evolutionary innovations occurred as soon as the temperature decreased to their upper temperature limits. Expand
Finding a second sample of life on earth.
There is a significant likelihood that at least one more sample of life, referred to here as alien life, may have emerged on Earth, and could have coexisted with known life. Expand
Chemosynthetic carbon metabolism in thermophiles
An important, previously-underestimated role for organic substrates in supporting chemosynthetic communities inhabiting geochemically diverse YNP hot springs is indicated and dominant autotrophs in these ecosystems are facultative. Expand
Applying the concept of the ecological niche and a macroecological approach to understand how climate influences zooplankton: Advantages, assumptions, limitations and requirements
This paper shows how observations from widely-spaced locations can be combined to characterise the ecological niche of a species, and how the concept of the niche can be used to understand and project how climate-induced changes in temperatures will alter marine zooplankton both locally and globally.

A Possible Mechanism for Evading Temperature Quantum Decoherence in Living Matter by Feshbach Resonance
It is proposed that the transition from a non-living to a living cell could be mapped to a quantum transition to a coherent entanglement of condensates, like in a multigap BCS superconductor. Expand
L'Evoluzione Biosferica è Grossolanamente Deterministica
Revival di un vecchio dibattito: "Riproduzione del nastro", Contingency vs Predictability in Evolution Qui rivedo una provocazione, secondo cui l'evoluzione del biota, incorporata nella biosfera, èExpand


The effects of heavy meteorite bombardment on the early evolution — The emergence of the three Domains of life
The interpretation of the molecular record suggests that life emerged early in Earth's history even before the time of the heavy bombardment was over, and the distribution of ecotypes on the rooted universal tree of life should not be interpreted as evidence that life originated in extremely hot environments. Expand
The universal ancestor lived in a thermophilic or hyperthermophilic environment.
If the LUCA was a progenote then the origin of life might have taken place at a high temperature, and the rRNA ancestral sequences reconstructed with maximum parsimony suggest that theLUCA lived in a thermophilic or hyperthermophilic environment. Expand
Life, Temperature, and the Earth: The Self-Organizing Biosphere
The idea that living things and the atmosphere, oceans, and soils comprise an interactive, self-regulating system-the Gaia concept-was first proposed nearly thirty years ago. Since then researchersExpand
The age of the Earth
Forty years ago, Patterson in his pioneering work on lead isotopes defined the age of the Earth and of the meteorites with 4.55 Ga. We reconsider the question of the age of the Earth and its relationExpand
An Estimate of the Age Distribution of Terrestrial Planets in the Universe: Quantifying Metallicity as a Selection Effect
Abstract Planets such as the Earth cannot form unless elements heavier than helium are available. These heavy elements, or “metals”, were not produced in the Big Bang. They result from fusion insideExpand
A cool early Earth
No known rocks have survived from the first 500 m.y. of Earth history, but studies of single zircons suggest that some continental crust formed as early as 4.4 Ga, 160 m.y. after accretion of theExpand
On the origins of cells: a hypothesis for the evolutionary transitions from abiotic geochemistry to chemoautotrophic prokaryotes, and from prokaryotes to nucleated cells.

The universal ancestor the authors infer was not a free-living cell, but rather was confined to the naturally chemiosmotic, FeS compartments within which the synthesis of its constituents occurred, leading to the emergence of prokaryotic lineages from inorganic confines. Expand
A younger age for the universe
A different standard Big Bang model, which includes cold dark matter with a cosmological constant, provides a consistent and absolutely time-calibrated evolutionary sequence for the universe. Expand
Terrestrial accretion rates and the origin of the Moon
Abstract The former decay of 182 Hf to 182 W ( T 1/2 =9 Myr) has resulted in variations in W isotope composition that reflect early solar system time-integrated Hf/W ratios. The bulk silicate EarthExpand
Evolutionary relationship of archaebacteria, eubacteria, and eukaryotes inferred from phylogenetic trees of duplicated genes.
A composite phylogenetic tree with two clusters corresponding to different proteins, from which the evolutionary relationship of the primary kingdoms is determined uniquely is proposed, revealing that archaebacteria are more closely related to eukaryotes than to eubacteria for all the cases. Expand
