Cow may be biggest mammal if humans keep up extinctions: Study

Oslo, May 12: The spread of humans around the world from Africa thousands of years ago wiped out big mammals in a shrinking trend that could make the cow the biggest mammal on Earth in a few centuries` time, a scientific study said on Thursday.

The spread of hominims - early humans and relatives such as Neanderthals - from Africa coincided with the extinction of mammals such as the mammoths, sabre-toothed tiger and glyptodon, an armadillo-like creature the size of a car.

"There is a very clear pattern of size-biased extinction that follows the migration of hominims out of Africa," lead author Felisa Smith of the University of New Mexico told Reuters of the study published in the journal Science.

Humans apparently targeted big species for meat, while smaller creatures such as rodents escaped, according to the report examining trends over 125,000 years.

In North America, for instance, the mean body mass of land-based mammals has shrunk to 7.6 kg (17 lbs) from 98.0 after humans arrived.

If the trend continues "the largest mammal on Earth in a few hundred years may well be a domestic cow at about 900 kg" (2,000 lbs), the U.S. team wrote.

That would mean the loss of creatures including elephants, giraffes and hippos. In March, the world`s last male northern white rhino died in Kenya.

But other research casts doubt on a continued shrinking of mammals, partly because of conservation efforts to stave off threats to wildlife such as climate change, loss of forest habitats and pollution and expanding cities.

Thomas Brooks, chief scientist of the International Union for Conservation of Nature (IUCN) who was not involved in the study, said the projection of ever smaller mammals was "doom and gloom."

"Happily I don`t think it`s very likely," he told Reuters, saying that other research suggests that large animals such as elephants are more likely to benefit in protected areas than smaller ones.

And a Red List of threatened species, maintained by the IUCN, also lists some wild mammals roughly the size of a cow - such as the African buffalo or the brown bear - as unendangered.

The Science study also excludes marine mammals such as the blue whale, the largest creature that has ever existed. It is endangered on the Red List but the populations are rising after a moratorium on hunts.

Smith said that "my optimist hat would like to say that it`s not going to happen because we love elephants`." But she said populations of large land mammals were falling and "declining population is the trajectory to extinction."

Voting has begun in 88 constituencies across 13 states and Union Territories amid a furious row between the Congress and the BJP over manifesto and inheritance tax. Election will be held on all seats of Kerala, a chunk of Rajasthan and UP.

Key points

Elections for the second phase will be held for 20 seats of Kerala, 14 seats in Karnataka, 13 in Rajasthan, eight each in Uttar Pradesh and Maharashtra, seven in Madhya Pradesh, five each in Assam and Bihar, three each in Bengal and Chhattisgarh and one each in Jammu and Kashmir, Manipur and Tripura.

Earlier, 89 constituencies were expected to vote in this phase. But polling in Betul, Madhya Pradesh, was rescheduled after the death of a candidate from Mayawati's Bahujan Samaj Party. Betul will now vote in the third phase, due on May 7.

Key candidates for this round include the BJP's Union minister Rajeev Chandrashekhar  -- up against Congress' Shashi Tharoor from Thiruvananthapuram; actors Hema Malini, and Arun Govil from 1980s iconic serial Ramayan, senior BJP leader Tejasvi Surya and Lok Sabha Speaker Om Birla,  Congress' Rahul Gandhi, KC Venugopal, Bhupesh Baghel. and Ashok Gehlot's son Vaibhav Gehlot.

For both BJP and the Opposition, the most crucial states in this phase will be Karnataka and Kerala. Karnataka is the only BJP bastion in the south, where the Congress won in the last assembly election. The party is hoping to do well amid concerns about delimitation and the disadvantage southern states could face after it.

Further south, the BJP is trying to break into the bipolar politics of Kerala. The party is hoping to open its account in the state having fielded Union ministers Rajiv Chandrasekhar and V. Muraleedharan. In Wayanand, a Congress bastion for over 20 years, it has fielded its state unit president K Surendran against Rahul Gandhi.

For the Opposition, Kerala is a big shining hope. Even though the Left and the Congress are competing against each other in the southern state, victory by either will add to the tally of the Opposition bloc INDIA. Kerala is one of the few states that have never sent a BJP member to parliament.

With north, west and northeast India saturated, the BJP is hoping to expand in the south and east in their quest for 370 seats. The party had won 303 seats in 2019, a majority of them from the Hindi heartland and bastions new and old, including Gujarat and the northeast.

The Congress, though, has claimed it would post a much better performance compared to 2019. After the first phase of the election, their claims have got louder, especially in Rajasthan and western Uttar Pradesh. Rashtriya Janata Dal chief Tejashwi Yadav has claimed INDIA will win all five seats in Bihar.  

The election is being held amid a bitter face-off between the Congress and the BJP. The row was sparked by Prime Minister Narendra Modi's comment that the Congress, if voted to power, will redistribute the personal wealth of people among "infiltrators" and won't even spare the mangalsutras of women. The Congress has questioned if the people had to fear for their wealth and mangalsutras in 55 years of the party's rule and accused the BJP of sidestepping issues that matter.

The next phase of election is due on May 7. The counting of votes will be held on June 4 – three days after the seventh and last phase of election on June 1.

Mangaluru: This year too, the Mangaluru International Airport has missed being designated as an embarkation point for the annual hajj pilgrimage. 

According to the Haj Committee of India, not many are choosing Mangaluru as an embarkation point. Last year, although Mangaluru was notified as one of the embarkation points, the Union government removed it from the list at the last minute.

Several associations and organisations submitted memorandums to the Haj Committee of India, requesting the reinstatement of Mangaluru as one of the embarkation points, but their efforts have not materialised this year either.

The use of Mangaluru Airport as an embarkation point for the haj began in 2010. In 2019, 1,400 haj pilgrims flew from MIA to Saudi Arabia.

“When the number is less, it is difficult to consider it. It was the same issue as last year,” reacted AP Abdullakutty, chairman of the Haj Committee of India.
Mangaluru as an embarkation point served people from undivided Dakshina Kannada, Kodagu, Shivamogga, Uttara Kannada, and Chikkamagaluru districts.
Last year, the Muslim Central Committee of Dakshina Kannada and Udupi districts submitted a memorandum to Abdullakutty. They expressed their disappointment with Abdullakutty and stated that Mangaluru had a good number of applicants ever since it was identified as an embarkation point. 
Now, they have to travel to Bengaluru. 

UT Khader, speaker of the Karnataka legislative assembly, pointed out that several Union ministries are involved in the process of designating embarkation points for the haj.

“We are not sure why MIA as an embarkation point was removed. Is it because of fewer applications, or are airlines not willing to bid for MIA as an embarkation point? Is it only an issue with MIA as an embarkation point, or are there other airports in the country facing similar issues? We will try to find out and seek answers. Meanwhile, we will also start working at the earliest so that MIA is considered as an embarkation point for hajj next year,” said Khader.

"I always wanted to be in a bar fight," said a US police official after pinning a Black man down on the ground and kneeling on his neck. The man later died at a hospital.

Ohio Police have come under intense scrutiny following the release of body camera footage showing officers pinning a Black man to the ground in a bar, reminiscent of the events that led to George Floyd's death in 2020.

The video, released by the Canton Police Department, captured the moments leading up to the death of Frank Tyson, a 53-year-old man suspected of leaving the scene of a single-car accident on April 18.

In the footage, officers are seen confronting Tyson inside a bar, where an altercation quickly ensues. Despite Tyson's pleas for help and his repeated cries of "I can't breathe," officers wrestle him to the ground and handcuff him, with one officer applying pressure to his back near his neck while saying, "You're fine." 

Tyson continues to plead for relief while lying on the floor. After several minutes, officers notice his lack of responsiveness and proceed to administer CPR. Paramedics arrive on the scene and transport Tyson to a local hospital, where he later dies.

In the body cam footage, one police officer can be heard bragging about how he always wanted to be in a "bar fight" with one of the patrons of the establishment. 

The circumstances surrounding Tyson's death draw chilling parallels to George Floyd's fatal encounter with Minneapolis Police in 2020 which sparked global outrage. 

The officers involved in Tyson's case, identified as Beau Schoenegge and Camden Burch, have been placed on administrative leave pending an investigation by the Ohio Bureau of Criminal Investigation.
