Researchers found that fish and flies can differentiate according to specific habitats within nine and 13 generations, respectively. These findings provide a basis for studying the role of natural selection in species evolution and offer insights into the processes of rapid speciation in nature.
A UMass researcher has found that new species can arise in as little as 12-14 generations, rather than the previously accepted maximum of 200-400 generations. This discovery suggests that adaptation can lead to reproductive isolation at a much faster rate than previously thought.
The University of California and Caltech are designing a 30-meter telescope called the California Extremely Large Telescope (CELT) to study distant galaxies and star formation. The telescope will have a segmented primary mirror made up of 1,080 small hexagonal mirrors, and its cost is estimated to be around $500 million.
Researchers discover that mobile DNA sequences, known as transposons, generate chromosomal inversions in the Drosophila fly. These inversions are found in small independent DNA sequences and have a positive role in evolution.
A new species of hominid, Australopithecus garhi, has been discovered in Ethiopia, providing significant evidence about the evolutionary connection between early humans and their ancestors. The fossil finds help fill a void in the East African record of human origins, spanning 2-3 million years ago.
Researchers May R. Berenbaum and Arthur R. Zangerl found that webworms and parsnips in the Midwest have adapted to each other, with levels of detoxification enzymes matching those of defensive compounds produced by plants. This suggests a reciprocal evolutionary change between interacting species.
A new species of spinosaurid dinosaur, Suchomimus tenerensis, is discovered in the Ténéré Desert with a long, narrow, crocodile-like skull. The fossil remains suggest that this predator had curved claws like giant meathooks and was about 11 meters long.
Evolutionary biologist H. Allen Orr proposes a new theory on the genetic foundations of adaptation, challenging standard theory that only tiny genetic changes contribute to adaptation. Orr's work uses mathematical modeling and computer simulations, suggesting that a mix of minor and major genetic changes can lead to adaptation.
Researchers Caro-Beth Stewart and Todd Disotell propose a new model for the evolution of humans and apes, suggesting that the common ancestor evolved in Asia rather than Africa. This theory requires only two hominoid migration events, marking a significant departure from traditional views.
A study by Washington University in St. Louis reveals that similar lizard communities have evolved independently on different islands in the Caribbean, converging on island habitats. The research found identical habitat specialists on each island, suggesting a unique response to environmental pressures.
Researchers believe a sudden shift in vegetation, triggered by changing atmospheric carbon dioxide levels and the dominance of C-4 grasses, led to a massive extinction event that wiped out many equine species. The long teeth of surviving horses allowed them to adapt to their environment, ensuring their survival.
A study of wild guppies in Trinidad found they can evolve between 10,000 to 10 million times faster than the fossil record. This suggests short-term experiments can provide insight into evolutionary changes over millions of years.
