Insects are the only invertebrates that evolved flight. Their wings are a marvel of engineering skill.
In a planetary circuit, electricity courses throughout Earth’s atmosphere and its surface. By 1749 Benjamin Franklin concluded that the properties of lightning were similar to those found in machines. This is also true of organisms on Earth, right down to their cells.
Animal pupils are attuned to lifestyle.
Life runs on a universal workforce: the proteins which build and maintain cells. Despite vast diversity, regardless of life form, the jobs proteins do are […]
Plants are constantly battling herbivores to avoid being eaten. One way they do so is to disguise their scent.
Spittlebugs are the nymphs of froghoppers. The nymphs are better known, as gardeners consider them especial pests.
Organisms adapt to new habitats but remember where they came from.
Some widely successful species, sometimes called “invasive”, outcompete by being versatile, such as having a broad diet. In being euryhaline – able to withstand wide-ranging salinity, the round goby is that. But what got the goby its widespread presence is an inner strength.
Only mammals chew their food. Mammals originally had their ears on their jaws.
Many animals employ fluorescence: a light show via various biochemical means with a diversity of intentions.
An organism’s habitat is the range of environmental conditions which are tolerable. Whereas organisms which adapt to specific niches are specialists, generalists have more tolerance.
Many orb weaver spiders sport lemony coats: a seemingly odd color choice, except that yellow attracts lunch.
Many moths sport luxurious scale pelts which make them look like fuzzy butterflies. The fuzz evolved as acoustic camouflage.
The term animal comes from the Latin animalis, meaning “having breath.” But not all animals breathe.
The plantain, a small plant native to Europe, has successfully spread around the world. Its success owes to savvy in adapting to local conditions.
Neoteny is the retention of features seen during early development in related species.
Bats have wondrous immune systems which are perpetually primed to handle viruses without getting sick. This training ground makes viruses more virulent.
Preferences for foods or mates may be passed to offspring before they are born: the phenomenon of instinct known as precocious knowledge.
Sociality is an exercise in communication. Nature inclines organisms to certain universal principles of social interchange, as researchers discovered when listening to jackasses talking.
There have been many mass extinction events on Earth. The one currently underway is somewhat novel.
It’s a hoary myth that humans evolved big brains to handle their multitudinous relationships.
In 2017, Indonesian archaeologist and caver Pak Hamrullah discovered a bevy of artwork in a cave on the island of Sulawesi that dates to 44,000 years ago.
Plants adapted to the presence of bats in at least 2 ways: to make it easier for bats to rid plants of potential pests, and for pollination services.
Eulipotyphlans are a taxonomic group of small mammals which include hedgehogs, gymnures (moonrats), solenodons, moles, and shrews of all sorts. Several eulipotyphlans are venomous. Eulipotyphlans with a vicious bite independently evolved this prey-catching assist several times.
Homosexuality has been a conundrum to evolutionary biologists who viewed behaviors from the peephole perspective of reproductive efficacy.
