Surprisingly, the evolutionary tree
is more a single vine (bold font) with a few small branches (fine font offshoots) than the old tree with many large branches.
The oldest fossils of a previously unknown ancient leopard species are shaking the pantherine evolutionary tree
, suggesting that big cats arose in Asia, not Africa, according to a new study.
Discovery of this new species was a shock to us because prior to this, the fossil record suggested that the evolutionary tree
of platypuses was a relatively linear one," Archer explained.
The research estimated that the evolutionary tree
split that led to horses on one branch and donkeys on the other happened about 4 million years ago.
Thousands of microRNAs have been identified in species up and down the evolutionary tree
since their initial discovery in worms nearly 20 years ago, suggesting they play a fundamental role in the cell's regulatory machinery.
Our ability to learn by observation has been hardwired into our nervous system many branches back on our evolutionary tree
A phylogeny is an evolutionary tree
reconstructed from its leaves (each of which represents a different species) by comparing DNA sequences or gene data with a plausible model of evolution.
After background chapters on important algorithms, general-purpose graphic processors, and massively threaded programming and reconfigurable computing with field-programmable gate arrays, researchers in the field present recent approaches to parallelize bioinformatics applications on a variety of parallel architectures, including pairwise and multiple sequence alignment, the basic local alignment search tool, motif finding, pattern matching, sequence assembly, hidden Markov models, proteomics, and evolutionary tree
They were not ancestors of people living today, but represented a "dead end" branch of the human evolutionary tree
Ever-more complex life forms emerged rapidly from there, eventually creating an evolutionary tree
with homo sapiens atop one of its branches.
The European samples were concentrated around the base of the evolutionary tree
Much of this information is neatly illustrated in an accurate and comprehensive figure of the spider evolutionary tree
