In this work, I argue that biology provides the basis for morality and that a Surthrival Principle forms its fundamental core. This principle best leads to humans' long-term success as a species. I describe how the Surthrival Principle, derived from established biological tenets, consolidates and accounts for various pronounced maxims (e.g., the Un...

Climate change, with its increasing frequency of environmental disturbances puts pressures on the livestock sec-tor. To deal with these pressures, more complex traits such as resilience must be considered in our managementstrategies and in our breeding programs. Resilient animals respond well to environmental challenges, and havea decreased probabi...

If you have ever been out to the countryside in the spring, you might have heard sheep bleating to their lambs. Sheep also bleat when they are separated from the flock or stressed in some other way. To us, all these bleats sound very similar. But do you think they also sound similar to the lambs? Or do you think the lambs know whose mother is calli...

Significance Knowledge of host–symbiont biogeography is critical to understanding fundamental aspects of symbiosis such as host–symbiont specificity. Marine animals typically acquire their symbionts from the environment, a strategy that enables the host to associate with symbionts that are well-suited to local conditions. In contrast, we discovered...
