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.
A newly discovered prehistoric fossil found in China is shedding light on parenting in reptiles from the Middle Jurassic, a new study says.
Many animals, including humans, are traditionally selfish creatures. If some organisms were as self-centered about parenting as they are about other lots in life, there would arguably be much fewer offspring in this world. Now researchers have identified brain mechanisms that help prospective parents have a change of heart and bond with their children.
