Many researchers may agree that birds might as well have written the book on parenting. While past research has found that some birds are expert "bad parents," now a new study has determined that birds can be "designer parents" as well, specifically hatching "juiced up" sons when feeling threatened.
Many will argue that there is no worse parent than one who abandons their child - especially for selfish reasons. Unfortunately, evolution doesn't select for what we think is "right" but for what works best. Now, new research has found that not only is abandoning a chick to be raised by others beneficial for zebra finches, but it may even be a trait that is selected for - improving the species as a whole.
It's no secret that for spiders and many other predator bugs, reproduction can quite literally involve courting death. The black widow, infamous as its own widow-maker, is one of the most iconic cannibal spiders around. Now a new study has revealed that male black widows have a fighting chance. They can smell if a female is hungry, helping them decide if courting her is worth the risk.
Scientists have discovered a fern "love child" in the mountains of France and found that it is the result of a puzzling reunion, providing insight on plant reproduction, according to a new study.
The massive 55 pound miracle seeds of the coco de mer palm are the stuff of legend. Now new research has determined that careful engineering and good "parenting" ensure these seeds grow to to such an impressive size.
Yes, those balls. You know the ones I'm talking about. The man rocks, the family jewels, the subject of that ACDC song we've all tried to forget about. In the great mammalian sex race, a male with big balls is likely a very successful reproducer, being both dominant and popular with the ladies. New research has found that with mice, however, that this isn't always the case. The best balls, experts are now claiming, don't always take up a lot of space.
Fertilization has always been seen as a race to the egg, where only the fittest and fastest sperm will be ever be able to naturally lead to new life. However, a new study has revealed that in the case of birds, this may not be the case. Instead, the longest and biggest avian sperm seems to get eggs "cooking," so to speak.
Corals may be in more trouble than we thought. A new study has recently revealed that even after corals recover from traumatic bleaching events, they may not reproduce, as bleaching appears to have some adverse affects on the long-term fertility of coral species.
Experts have long known that human activity can influence how local animals live, including their habitats, food sources, and even behavior. However, a new study has found that we can even impact how an animal procreates, changing the size and structure of specific fish species' genitalia in only a few decades.
Some female frogs are making their offspring grow faster in the midst of global warming, new research shows, adjusting the rate depending on the date of reproduction.
In a stunning turn of events, it has been scientifically confirmed that the offspring of a virgin captive snake named Thelma are hers and hers alone, boasting no genetic information from a male parent. This is a remarkably rare example of a "virgin birth," a natural phenomenon that still leaves experts scratching their heads.
Apparently reptiles have an ultimatum in life. Live hard and die young, or live long and healthy lives by abstaining from sex and meat.
You may be familiar with the idea that the young are the legacy and backbone of any community, leaving the old to grow fat and retire without a care in the world. It would be nice to think that this romantic concept applies to animal populations too. However, researchers are arguing that this is just not the case. Fisheries are extremely dependent on their old, slow, but still fertile females to keep populations up.
Experts have long thought that the pelvic bone that floats unattached to the rest of a whale's skeleton is simply an evolutionary throwback from when their ancestors boasted four flippers. Now, researchers argue that whales actually are using this seemingly useless bone for very specific mating purposes.
