Unlike most monkeys, apes do not have tails. Apes also have broad chests and shoulders that allow them to swing from branch to branch (a form of movement known as brachiation). Apes generally have larger brains than monkeys (and most other animals), and several are known to use tools. ...
Courtship display – a suite of behaviours displayed by an individual to attract and eventually reproduce with an individual of the opposite sex – is an essential feature of animals, fulfilling a variety of crucial functions such as sex recognition, sexual stimulation, synchronization of mating behav...
Separate sexes and sex-biased gene expression have repeatedly evolved in animals and plants, but the underlying changes in gene expression remain unknown. Here, we studied a pair of plant species, one in which separate sexes and sex chromosomes evolved recently and one which maintained hermaphrodite...
Would you believe one of the most complete pictures ever ofvertebrate evolution? Led by Professor of Organismic and Evolutionary Biology and Molecular and Cellular Biology Hopi Hoekstra, a team of international researchers conducted a years-long study in which hundreds ofmicewere released into massive,...
The scientists inspected how two different isotopes (or forms) of carbon fluctuated during these volcanic eruptions. They discover that the "heavy" form of carbon was depleted relative to the "light" form. Labels: Dinosaur animals, Dinosaur reptile, Dinosaurs, Extinction of Dinosaurs posted by Ta...
DreamPictures/Getty Images As the animals we are, humans only need a few things to continue along as a species. We need to find food. Being omnivores, we have a wide selection available to us. We have to find clean water to drink. We need shelter to protect us from the elements. ...
49. Wild One The photos in this post were taken in December, when I came across a Giant Cuttlefish off the Sydney coast in a den where I’ve encounteredmanyof the most spectacular animals pictured on this website. When cuttlefish are common in the area, this seems to be one of the ...
[9,20]. In contrast, aquatic carnivorous plants mostly grow in shallow standing, oligo-mesotrophic and dystrophic waters. They exhibit much higher photosynthesis rates and growth rates than terrestrial carnivorous plants and similar rates to non-carnivorous aquatic plants [2,20,21]. Prey animals ...
in the water yet had latent tetrapod characteristics. Until recently, these tetrapod ancestors nearly all hailed from fossil deposits in the northern Atlantic, but the discovery of Gogonasus in Australia has put the kibosh on the theory that land-dwelling animals originated in the northern ...
Apart from a couple of bothersome side branches, horse evolution presents a neat, orderly picture of natural selection in action. The basic storyline goes like this: as the woodlands of North America gave way to grassy plains, the tiny proto-horses of theEoceneEpoch (about 50 million years ...
