Plants that have flowers that point towards the sky may be better at attracting moth pollinators than plants that have 'shy' flowers that point sideways.
Karyotype is usually a stable feature of each species since chromosomal changes, if they occur, may contribute to the formation of barriers between populations causing the establishment of reproductive isolation and speciation ...
Plants or animals using color to attract a mate is fairly common in nature, but for Phlox drummondii, a wildflower commonly known as Drummond's phlox, just the opposite is true.
Why do crosses between closely related species fail to produce fertile hybrids? A new study led by Professor Axel Imhof of Ludwig-Maximilians-Universitaet (LMU) in Munich, Germany, shows that differences in the levels - not ...
Researchers from Macquarie University and the University of New South Wales have discovered a strange mechanism whereby two species of traumatically inseminating plant bug are able to live together in Tahiti, as published ...
Darwin referred to the origin of species as "that mystery of mysteries," and even today, more than 150 years later, evolutionary biologists cannot fully explain how new animals and plants arise.
(Phys.org)—new paper by researchers at the University of Notre Dame provides new insights into speciation, which is the evolutionary process by which new biological species arise.
China's endangered wild pandas may need new dinner reservations – and quickly – based on models that indicate climate change may kill off swaths of bamboo that pandas need to survive.
European scientists investigated differences in the genomes of various distantly-related yeast and their effects on cell survival. Results may provide insight into cell death induced by free radicals.
Evolution of species remains a hot topic since Darwins theory of natural selection. A European initiative addressed the issue of speciation from the viewpoint of reproductive isolation.
