The new technology of high-throughput DNA sequencing allowed a better analysis of the whole genome.
Draft Sequence of the Neandertal Genome
The problem with this faster and cheaper technique, when compared to the Sanger approach, is that the length of DNA that can be read in any single sequencing run is much shorter and therefore difficult to analyze.
Check out the seminal paper here: You are commenting using your WordPress. We show that Neandertals shared more genetic variants with present-day humans in Eurasia than with present-day humans in sub-Saharan Africa, suggesting that gene flow from Neandertals into the ancestors of non-Africans occurred before the divergence of Eurasian groups from each sequece.
An interesting article I found describing genetic comparisons between Neanderthals and humans. A Draft Sequence of the Neandertal Genome https: By analyzing 14, potentially interesting protein coding regions of the Neandertal DNA and alignment with human data is was possible to identify 88 amino acid substitutions that uniquely fixed in humans. Science How much of a Neanderthal are you? Comparisons of the Neandertal genome to the genomes of five present-day humans from different parts of the world identify a number of genomic regions that may have been affected by positive selection in ancestral modern humans, including genes involved in metabolism and in cognitive and skeletal development.
All these steps were undertaken in a so-called clean-room laboratory of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, in order seqhence prevent the sample DNA from neaneertal contamination. Through the use of microarray technology and the previous data a different team of researchers 3 succeeded in doing so.

Altmetric This page is provided by Altmetric. However the PCR method is not useful for analysing genomes on a large-scale as the researchers aimed for in the present swquence. The approach the researchers took was rather special and in the following I want to try to explain why. Furthermore, when Green et al. Among others, genes venome were affected by those fixed changes are for example ABC transporters, potassium channels, G-protein coupled receptors and certain transcription factors.
Science New York, N. Find all citations in this journal default. Since Neandertals are our closest kin such a comparison is of greatest value. Sequences with significantly better matches to the primate genomes than to other sequences within the database were further analyzed. In addition seequence conclusion on the question whether Neandertals and humans ever have interbred could be made.

She is quoting study from that only compared FIVE people. Gene Ontology GO Terms. The following sequencing process can be subdivided into several steps unique steps that were special for this research project. In order to purify and glue the puzzle pieces of the now sequenced Neandertal DNA together bioinformatic tools were used. JonathanStone10 VolcanoJenni as long as their authorship is justified, e. PopSci Depending on your specific ancestory, non-African individuals i.
