"I feel your pain." Anyone in pain appreciates such an expression of empathy, but could these words be truer than we realize?

Arguably, one of the most underappreciated designs in animals are the social transfers of emotions and feelings. Mice experiments conducted by three behavioral scientists at Stanford University led by Monique Smith sought not only to determine the degree and extent of social transfer of empathy but also the means and pathways.1 Their results carry implications for evolution and creation.

Biologists typically define empathy as the adoption of another individual's sensory and emotional state. Field studies establish that humans are not alone in expressing and experiencing empathy. Empathy has been observed in nearly every social mammalian species. Hence, it is possible to use social mammals as proxies to develop therapeutic tools for human neural disorders.

The three behavioral scientists chose mice as their proxy since it is known that for both humans and rodents the anterior cingulate cortex (ACC) in the brain encodes information about the affective state of other individuals.2

Behavioral Experiments
In one experiment, Smith's team injected a drug into a mouse that induced long-lasting arthritis-like pain. The experimenters allowed another mouse, a cage-mate of the injected mouse, to socially interact with the injected mouse for one hour. This one-hour exposure resulted in the bystander mouse experiencing the pain of the injected mouse for the next four hours. When the injected mouse received a morphine shot with subsequent pain relief, the bystander mouse almost immediately experienced relief from the socially transmitted pain.

In a second experiment, Smith's team repeatedly shocked one mouse while a second nearby mouse watched. Both mice exhibited the same freeze posture response to the shock-induced fear.

Through the use of specific drugs and circuit neuroscience tools, Smith's team determined that different neural pathways in the brain were involved in the social transfers of pain and pain relief compared to fear. The neural pathway for pain and pain relief is from the ACC to the nucleus accumbens (NAc), whereas the neural pathway for fear is from the ACC to the basolateral amygdala (BLA).

Potential Treatment Applications
Both chronic and temporal pain from severe trauma pose therapeutic challenges. Smith's team's experiments indicate that what works for mice might also work for humans. Someone experiencing severe pain may experience relief simply by observing another human with whom they have had significant social interaction. Such social interaction could substantially reduce reliance on pain-relieving drugs and help combat addictions. The immediate and long-term health cost savings would be substantial.

Another major potential health benefit arising from the research lies in the treatment of brain injuries, brain disorders, and genetic brain handicaps where human subjects have lost some empathetic capabilities. Using animal subjects to determine the specific locations in the brain and pathways in the brain responsible for expressions and experience of empathy would greatly assist medical researchers in finding therapies, and even cures, for empathy-related brain disorders.

Life Design Implications
The origin of emotions and empathy in animals poses a huge challenge to naturalistic evolution. While certain chemicals can govern the degree to which emotions and empathy is expressed or experienced, no deterministic explanation for the origin of emotions and empathy has yet passed scientific scrutiny and testing. From a creation perspective, Genesis 1 uses the Hebrew verb, bara, meaning in the context of Genesis 1, to create something brand new that did not exist on Earth before. The creation of animals capable of using emotions and empathy to bond with one another and to sacrifice for one another indicates a nonphysical origin for emotions and empathy.

Birds and mammals have been endowed with the capacity to express and experience emotions and empathy such that they are able to form life-long bonds with one another and make sacrifices to meet one another's needs. Such endowment makes it possible to tame these animals so that they serve and/or please humans. A discovery like this one, where scientists use animal designs to find ways to relieve pain marks one great way that animals serve us. The fact that humans, birds, and mammals share in common many design features relevant to the expression and experience of emotions and empathy challenges an evolutionary origin but supports creation.

About The Author

Dr. Hugh Ross

Reasons to Believe emerged from my passion to research, develop, and proclaim the most powerful new reasons to believe in Christ as Creator, Lord, and Savior and to use those new reasons to reach people for Christ. I also am eager to equip Christians to engage, rather than withdraw from or attack, educated non-Christians. One of the approaches I’ve developed, with the help of my RTB colleagues, is a biblical creation model that is testable, falsifiable, and predictive. I enjoy constructively integrating all 66 books of the Bible with all the science disciplines as a way to discover and apply deeper truths. 1 Peter 3:15–16 sets my ministry goal, "Always be prepared to give an answer to everyone who asks you to give the reason for the hope that you have. But do this with gentleness and respect, keeping a clear conscience." Hugh Ross launched his career at age seven when he went to the library to find out why stars are hot. Physics and astronomy captured his curiosity and never let go. At age seventeen he became the youngest person ever to serve as director of observations for Vancouver's Royal Astronomical Society. With the help of a provincial scholarship and a National Research Council (NRC) of Canada fellowship, he completed his undergraduate degree in physics (University of British Columbia) and graduate degrees in astronomy (University of Toronto). The NRC also sent him to the United States for postdoctoral studies. At Caltech he researched quasi-stellar objects, or "quasars," some of the most distant and ancient objects in the universe. Not all of Hugh's discoveries involved astrophysics. Prompted by curiosity, he studied the world’s religions and "holy books" and found only one book that proved scientifically and historically accurate: the Bible. Hugh started at religious "ground zero" and through scientific and historical reality-testing became convinced that the Bible is truly the Word of God! When he went on to describe for others his journey to faith in Jesus Christ, he was surprised to discover how many people believed or disbelieved without checking the evidence. Hugh's unshakable confidence that God's revelations in Scripture and nature do not, will not, and cannot contradict became his unique message. Wholeheartedly encouraged by family and friends, communicating that message as broadly and clearly as possible became his mission. Thus, in 1986, he founded science-faith think tank Reasons to Believe (RTB). He and his colleagues at RTB keep tabs on the frontiers of research to share with scientists and nonscientists alike the thrilling news of what's being discovered and how it connects with biblical theology. In this realm, he has written many books, including: The Fingerprint of God, The Creator and the Cosmos, Beyond the Cosmos, A Matter of Days, Creation as Science, Why the Universe Is the Way It Is, and More Than a Theory. Between writing books and articles, recording podcasts, and taking interviews, Hugh travels the world challenging students and faculty, churches and professional groups, to consider what they believe and why. He presents a persuasive case for Christianity without applying pressure. Because he treats people's questions and comments with respect, he is in great demand as a speaker and as a talk-radio and television guest. Having grown up amid the splendor of Canada's mountains, wildlife, and waterways, Hugh loves the outdoors. Hiking, trail running, and photography are among his favorite recreational pursuits - in addition to stargazing. Hugh lives in Southern California with his wife, Kathy, and two sons.
