Sharks have been on the planet for 450 million years and have survived all 5 mass extinctions. However, all 440 species of sharks are currently under threat from humans. 100 million sharks are killed every year due to human activity, and if we do not stop this brutal massacre of sharks, ...
High-throughput sequencing projects generate genome-scale sequence data for species-level phylogenies. However, state-of-the-art Bayesian methods for inferring timetrees are computationally limited to small datasets and cannot exploit the deluge of new genomes. In the case of mammals, molecular-clock ...

Flecks of carbon trapped inside grains of zirconsuggest thatlife exists at this time, but the evidence is limited. 3.9 billion years ago? TheLast Universal Common Ancestor(LUCA),the species from which everything alive today is descended,may live at this time according to genetic evidence.Attempts...
Evolution is the process by which species of organism undergo change over a period of time through natural selection. The genetic makeup of organism is traced using fossils or DNA technology. Science is a way of understanding nature and developing explanations for stuctures. Science does not pro...

For comparison we used the same method to estimate the time of origin of 27 retrogenes that recruited introns by chimerization [8]. We mapped the results on the vertebrate phylogeny (Additional files 56 and 7). The timeline and divergence time of species in the phylogeny were reconstructed ...
