Evolution During The Cambrian Explosion

A new study by an international team of scientists has revealed the developmental and evolutionary mechanisms underlying the origin of a major phylum.

Since the discovery of submarine hydrothermal vents around 40 years ago, these natural chemical reactors have been a focus for evolutionary researchers searching for the origin of life.

Rules Of Life: From A Pond To The Beyond

The Cuatro Cienegas Basin, located in Chihuahuan Desert in Mexico, was once a shallow sea that became isolated from the Gulf of Mexico around 43 million years ago.

One of the chief paradoxes of molecular oxygen (O2) is that it is an essential requirement for multicellular eukaryotes on Earth while simultaneously posing a threat to their survival via the formation of reactive oxygen species.

When the Earth was born, it was a mess. Meteors and lightning storms likely bombarded the planet's surface where nothing except lifeless chemicals could survive.

Animal Embryos Evolved Before Animals

Animals evolved from single-celled ancestors, before diversifying into 30 or 40 distinct anatomical designs. When and how animal ancestors made the transition from single-celled microbes to complex multicellular organisms has been the focus of intense debate.

The origin of eukaryotes remains enigmatic. Current data suggests that eukaryotes may have risen from an archaeal lineage known as "Asgard archaea".

The air, earth and water of our planet are pulsating with living things. Yet, a vast and diverse web of life exists, about which almost nothing is known. This is the world of flagellates, tiny organisms that persist in staggering numbers in many diverse ecosystems around the world.

University of Wisconsin-Madison researchers have cultivated lifelike chemical reactions while pioneering a new strategy for studying the origin of life.

The discovery of giant viruses with large genomes has transformed our understanding of the limits of viral complexity in the biosphere, and subsequent research in model virus-host systems has advanced our knowledge of intricate mechanisms used by these viruses to take over host cells during infection.
