Paragraph: The idea that the domestic dog descended from the grey wolf was originally established in 1993 using comparisons of wolf and dog mitochondrial DNA. This investigation showed that no other living animal was more closely related to the domestic dog than the grey wolf: “The domestic dog is an extremely close relative of the grey wolf, differing from it by at most 0.2% of [mitochondrial DNA].” Mitochondrial DNA is passed down by the mother (without any genetic contribution from the father) and changes only through random mutations that occur from generation to generation. Scientists use this much smaller and separate DNA sequence to estimate when populations of animals first diverged and to estimate the evolutionary relationships between organisms. By the mid-2000s, new technology allowed scientists to map the much longer DNA sequence found on the chromosomes of wolves and dogs — the genes that actually code for physical traits and behaviors. These studies demonstrated a 99.9% similarity (technically 99.96%) between dog and grey wolf, as covered in a 2007 review paper on the topic: In general, the domestic dog is an extremely close relative of the grey wolf, from which it differs by only ~0.04% in nuclear coding-DNA sequence, and no dog [mitochondrial DNA] sequences have been found that show closer kinship to other canid species. This similarity is so profound that hybridization often occurs between dogs and wolves. By the biological definition of species, this would mean that the domestic dog is a subspecies of the grey wolf (canis lupus familiaris). There remains some debate, however, as to what the appropriate classification for the domestic dog would be, with some arguing that the domestic dog should be its own distinct species (canis familiaris). Claim: Dogs and wolves are genetically 99.9% identical.
These advances in genetic analysis have allowed scientists as well to pin down the probable timing of the split between these two canid lineages. A study published in 2015, which compared the whole genome sequence of dogs to a 35,000 year old Siberian wolf specimen, suggested the split likely occurred between 27,000 and 40,000 years ago, and that domestic dogs are likely themselves the descendants of a now extinct descendant of grey wolves.

Paragraph: "Senate Republicans’ surprise move to repeal the requirement to have health insurance into their tax reform bill revealed numbers that few people had noted before. (The mandate says that everyone must have coverage or face a fine.) ""80 percent of the tax falls on those who make $50,000 a year or less,"" Sen. John Thune, R-S.D., told Fox News Nov. 15. ""We’re taking a failed policy that punishes people with taxes -- low-income people. (We’re) taking that tax away, giving them tax relief there, and then ploughing that back into tax relief for middle-income families."" This was no throw-away line. Thune is the third-ranking Republican in the party’s Senate leadership, and his colleagues delivered similar versions of the talking point throughout the day. In 2016, the fine for not having insurance stood at $695 for adults. The formula has a few wrinkles that brought the maximum penalty to $2,085 for a family, or 2.5 percent of income, whichever was larger. Going forward, it rises with inflation (unless of course, Congress repeals it). Not everyone without insurance has to pay the fine. The list of exemptions is long. It includes a family with income under $20,800; people who have suffered domestic violence in the household; anyone who has suffered the death of a close family member; someone who has received a utility shut-off notice, and more. Thune’s office said he got his information from 2015 data from the Internal Revenue Service. In one key sense, Thune is correct. Out of all the tax returns sent to the IRS that included a payment of the fine, 79 percent came from households making $50,000 a year or less. (Technically, the income is adjusted gross income, which understates actual income. But on average, the adjustment makes little difference for this check.) However, Thune didn’t specify that he was talking about the number of people. His description of the tax could just as equally refer to the dollars paid. The government collected a little over $3 billion from about 6.6 million households. Of that, about $1.8 billion, 60 percent, came from households with incomes under $50,000. So in dollar terms, about 60 percent of the tax fell on people in that income range, not the 80 percent that Thune said. Thune’s communications staff told us he was talking about the number of people and the number of returns. We reached several health care and tax researchers, and none of them challenged the core numbers. Gordon Mermin with the Urban-Brookings Tax Policy Center ran the numbers and found that as a percentage of income, the tax fell heaviest on the $25,000 to $50,000 group. On average, that group paid 3.1 percent of income. Mermin told us households in this range are more likely to lack insurance, and due to their incomes, are less likely to be able to claim an exemption from the fine. ""People shouldn’t be surprised the $25,000 to $50,000 group is affected the most,"" Mermin said. But researchers found it odd that people making less than $25,000 had paid as much as they did. The $10,000 to $25,000 group accounted for 22 percent of the payments, and about 36 percent of the households. ""Folks are just making a mistake,"" said Jonathan Gruber, one of the architects of Obamacare and an economist at the Massachusetts Institute of Technology. ""Given the exemptions, there is no way such low-income folks should be paying."" The IRS knows this has happened. It’s been sending out letters since 2015, telling filers ""it appears that you may have reported owing too much Health Care Shared Responsibility Payment,"" the penalty’s formal name. ""The IRS has reached out to some taxpayers to let them know they’ve overpaid the penalty, but they don’t have the capacity to do that in all cases,"" said Tara Straw at the Center for Budget and Policy Priorities, a liberal-leaning think tank. Straw said the IRS targets people who automatically qualify for an exemption because of their income, a factor that is stronger in states that did not expand Medicaid to people making 138 percent of federal poverty. Where the IRS effort falls short, she said, relates to personal circumstances such as a death in the family or a utility service cut-off notice. Larry Levitt at the Kaiser Family Foundation, a neutral source of health care data, also agreed that ""there certainly appear to be some low-income people paying the penalty who could be claiming an exemption."" A just-released study from Kaiser suggests the number could be large. The report found that about 5 million uninsured people could get coverage for less than the cost of the penalty. Thanks to the subsidies in Obamacare, the lowest-level plans would be free to many of those people, or if not free, available at a very low cost. If  everyone took advantage of those subsidies, the 6.6 million households paying the penalty because they lack coverage would fall significantly. We don’t know how the numbers would shake out because about 4 million people neither paid the fine nor told the IRS that they had coverage. Republicans offer the repeal of the penalty as a boon to working Americans, and for some it would be. But the Congressional Budget Office, the nonpartisan analytic arm of Congress, has found that removing the penalty makes it less likely that people will seek out insurance, even if it would be free or very affordable. Thune said that 80 percent of the individual mandate penalty falls on those who make $50,000 a year or less. In terms of the number of returns in which people paid the fine, that figure is correct. In terms of the dollars collected, it overshoots the mark. People in that income range account for about 60 percent of the payments. Still, an independent analysis showed that households in the $25,000 to 50,000 income range paid the highest percentage of income on the penalty. There’s strong evidence that many lower income people are paying the fine by mistake, and millions could both avoid it and gain health coverage for less than the cost of the fine. But as far as who is paying the fine." Claim: 80 percent of the (individual mandate) tax falls on those who make $50,000 a year or less.

Paragraph: Staff of the Maubeuge zoo noticed when they arrived for work that the security door of the feline’s pen had been forced open, the officials said. Police are checking footage from the zoo’s video surveillance system. The panther caused panic last week in Armentieres, a town close to the Belgian border, when it was spotted walking on a roof. The feline had been able to slip out after its owner, a private individual who had been keeping the panther in their home, had left a window open. The owner is wanted by police for keeping a dangerous animal in a private residence. After the escape, the fire brigade managed to catch the panther, and it was subsequently transferred to the Maubeuge zoo. The animal is a six-month old female, according to a local animal protection organization. Claim: Rigevidon can cause blood clots, strokes, and burst aneurysms.

A young black panther that escaped last week and was seen prowling the rooftops of a northern French town has been stolen from the zoo where it was held after being recaptured, police and city officials said on Tuesday.
