A new study comparing 59 species of primates linked same-sex sexual behavior to scarce resources and more predators in ...

Science has treated same-sex sexual behavior as an “evolutionary conundrum” because it (generally) doesn’t help animals to reproduce, thus ensuring that their genes get passed down and their species ...

The study of animal behaviour in ecological and evolutionary contexts examines how behavioural traits develop, persist and interact with environmental challenges. Research in this field investigates ...

More than 59 different primate species have been observed participating in some kind of same-sex behaviors, making it extremely common.

Same-sex behavior is widespread in primates and may help strengthen social bonds and improve survival under challenging ...

Homosexual behavior is much more common across the animal kingdom than we first thought, new research has found. Scientists found that 78 percent of animal behavior experts had seen some degree of ...

Evolutionary approach to animal behavior -- Diversity of behavior -- Genetics of behavior -- Development of behavior -- Nerve cells and behavior -- Organization of behavior -- Evolution of behavior: ...

The peppered moth is an iconic example of Charles Darwin’s theory of evolution by natural selection. For centuries peppered moths (Biston betularia) were common in the forests around Manchester, ...

We project a great deal onto animals. They are elevated into ideals of love and fidelity (dogs, horses), and often they are reduced to objects and tools (cattle, pigs, horses again). Much of ...

Trying to understand human behavior (a basic feature of our species, shaped by natural selection) without understanding evolutionary principles would be like trying to understand the details of a car ...
