Q: The domestic dog (Canis lupus familiaris or Canis familiaris) is a domesticated canid which has been selectively bred for millennia for various behaviors, sensory capabilities, and physical attributes.

Although initially thought to have originated as a manmade variant of an extant canid species (variously supposed as being the dhole, golden jackal, or gray wolf), extensive genetic studies undertaken during the 2010s indicate that dogs diverged from an extinct wolf-like canid in Eurasia 40,000 years ago. Being the oldest domesticated animal, their long association with people has allowed dogs to be uniquely attuned to human behavior, as well as thrive on a starch-rich diet which would be inadequate for other canid species.

Dogs perform many roles for people, such as hunting, herding, pulling loads, protection, assisting police and military, companionship, and, more recently, aiding handicapped individuals. This impact on human society has given them the nickname "man's best friend" in the Western world. In some cultures, however, dogs are a source of meat.

Q: (CNN) -- Risking their lives to help disadvantaged Afghans became almost a norm for Tom and Libby Little.

"We raised our three daughters through what was, at times, just hell," Libby Little said. "A hundred rockets a day was a good day."

Family members lived underground to avoid bombings, she said. Yet they stayed out of a love for the people and a passion for providing eye care for the needy.

But violence prevailed on Thursday.

Tom Little, a New York optometrist, was among 10 people killed by gunmen in Badakhshan, a remote northeastern region of the country. The mostly foreign members of a medical team were robbed and shot one-by-one on a remote road. Their bodies were transferred to Kabul early Sunday, authorities said.

The Taliban claimed responsibility for the attack.

"He died right where he loved to be -- and that was doing eye care in remote areas," Little said from her home in New York. "Our daughters are missing him terribly. But I think their feeling is, too, that this is a real passion that he had."

More than 400 people gathered Sunday at Loudonville Community Church in Loudonville, New York, to honor Little. The church supported his trip financially and emotionally.

"Four weeks ago, Tom Little stood right here," an emotional Stan Key, senior pastor, told the congregation.

The church had printed Wednesday in its weekly worship guide, "Praise the Lord that Tom's ministry in conducting outpatient clinics ... in a remote village was successful. God protected Tom and his team." Key said he decided to leave it in the guide even after hearing the news of Little's death.

Q: Mariupol, Ukraine (CNN)Ukraine President Petro Poroshenko declared a ceasefire went into effect at midnight Saturday local time (5 p.m. ET) between the Ukrainian military and pro-Russian militants in the nation's east.

The separatist Donetsk People's Republic also announced the ceasefire.

But an apparent violation was reported less than 90 minutes after the ceasefire began when Ukraine's Anti-Terrorist Operation Command reported that a military post near Zolote in the Luhansk region has been shelled by mortars.

As a positive sign, CNN reporters in Ukraine reported the shelling quieted shortly after midnight.

The peace agreement signed in Minsk, Belarus, several days ago comes with many questions over how it will be implemented and whether it will stick. Mistrust is high on both sides, adding to the doubts.

The town of Debaltseve, a strategically located railroad hub in the east, is shaping up as a crucial piece of the ceasefire.

In his speech announcing the ceasefire, Poroshenko said Ukrainian troops control the town and warned militants to stay away.

"I think the fact of using the tense situation on the outskirts of Debaltseve by militants-terrorists-mercenaries poses a great threat, which can violate the ceasefire regime," Poroshenko said. "I am warning all participants of the Minsk negotiations, including the Russian Federation, which identifies itself as the guarantor of the reached agreements."

CNN's Nick Paton Walsh, reporting from the eastern town of Donetsk, said separatists claim to have encircled Debaltseve.

"Debaltseve will be a vital flashpoint for the hours ahead," he said.

Poroshenko has warned that if the separatists do not abide by the ceasefire, he will impose martial law throughout Ukraine's territory, his spokesman Andrey Zhigulin told CNN.
