Evolutionsgeschichte

Phylogenetische Bäume
Phylogenetic trees come in many forms. It matters in which sequence the organisms are arranged from the bottom to the top of the tree, but the…
Verhältnisse auf der frühen Erde
Around 4 billion years ago, oceans began to condense on earth while volcanic eruptions released nitrogen, carbon dioxide, methane, ammonia, and…
Die Besiedlung des Landes
Changes in the environment of the early Earth drove the evolution of organisms. As prokaryotic organisms in the oceans began to photosynthesize, they…
 Was ist Evolutionsgeschichte?
Scientists record evolutionary history by analyzing fossil, morphological, and genetic data. The fossil record documents the history of life on Earth…
 Der Beweis für die Evolution
Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the…
 Der Fossilienbestand
The fossil record documents only a small fraction of all organisms that have ever inhabited Earth. Fossilization is a rare process, and most…
 Konvergente Evolution
Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection…
Ultra-lange lesen Sequenzierung für ganze genomische DNA-Analysen
Third generation single-molecule DNA sequencing technologies offer significantly longer read length that can facilitate the assembly of complex…
Verfahren für Adaptive Labor Entwicklung von Mikroorganismen Mit einem Chemostat
Natural evolution involves genetic diversity such as environmental change and a selection between small populations. Adaptive laboratory evolution…
Wholemount In Situ Hybridisierung für <em>Astyanax</em> Embryonen
In recent years, a draft genome for the blind Mexican cavefish (Astyanax mexicanus) has been released, revealing the sequence identities for…
Manipulation der Genfunktion in mexikanischen Cavefish
Cave animals provide a compelling system for investigating the evolutionary mechanisms and genetic bases underlying changes in numerous complex…
