Jane Goodall, the trailblazing primatologist who taught the world about chimpanzees and their striking similarities to humans, has died at the age of 91.

Her death was announced by her foundation, the Jane Goodall Institute (JGI), on Wednesday. 

According to the organization, Goodall passed away earlier that morning "due to natural causes."

"She was in California as part of her speaking tour in the United States," the statement said.

The institute added, "Dr. Goodall’s discoveries as an ethologist revolutionized science, and she was a tireless advocate for the protection and restoration of our natural world."

Goodall's fascination with primates began at an early age. Remarkably, she earned a PhD in ethology from the University of Cambridge in the mid-1960s, one of few students admitted without holding a prior bachelor's degree.

In 1960, she discovered that chimpanzees can use and make tools, which the JGI called "one of the greatest achievements of twentieth-century scholarship." She founded her institute, which has become a prominent conservation NGO, in 1977.

"She took an unorthodox approach in her field research, immersing herself in their habitat and their lives to experience their complex society as a neighbor rather than a distant observer and coming to understand them not only as a species, but also as individuals with emotions and long-term bonds," the institute noted.

In 1991, she founded the Roots & Shoots program, a youth movement focused on conservation and humanitarianism. 

Most recently, Goodall was given the Presidential Medal of Freedom by former President Joe Biden at the beginning of 2025.

Her death led to an outpouring of grief on social media. In one post, the San Antonio Zoo wrote that it was "devastated" by the news.

"She spent her life advocating for chimpanzees and all wildlife," the zoo's post read. "Her goal was to help people understand the true nature of animals and that each individual animal is important. While her work, words and passion will live on, we send our thoughts and prayers to her family, friends and colleagues."

The United Nations also honored Goodall in a message on X.

Today, the UN family mourns the loss of Dr. Jane Goodall," the UN's post read. "The scientist, conservationist and UN Messenger of Peace worked tirelessly for our planet and all its inhabitants, leaving an extraordinary legacy for humanity and nature."

Judge Arun Subramanian rejected Sean "Diddy" Combs' request for a new trial and the rapper's demand for an acquittal days before his scheduled sentencing.

Subramanian said the prosecution provided "overwhelming evidence" of Diddy's guilt on the charges of transportation to engage in prostitution.

"The government proved its case many times over," the federal judge wrote in his opinion obtained by Fox News Digital. "That by itself might be enough to dispose of Combs’s challenge. But the other factors don’t do much to help Combs either."

The rapper's legal team had argued the sex trafficking and racketeering evidence could have prejudiced the jury. Judge Subramanian also rejected the "spillover prejudice" argument, pointing to the split verdict. "It weighs heavily that the jury declined to convict him on any of the counts related to that conduct," Subramanian wrote. "Had the prejudice indeed been so great, one would expect a jury to convict on the most relevant counts before it could spill over and infect the others."

DIDDY'S EX CASSIE FEARS ‘SWIFT RETRIBUTION’ IF RAPPER WALKS FREE AS PROSECUTORS PUSH FOR 11-YEAR SENTENCE

A jury convicted Diddy on two counts of transportation to engage in prostitution on July 2. The "I'll Be Missing You" rapper was acquitted of his most serious charges – racketeering and sex trafficking.

Diddy could spend a maximum of 20 years behind bars, 10 years for each count he was convicted of. The prosecution recommended 135 months (just over 11 years) for his sentencing.

The prosecution claimed Diddy deserves a "substantial" prison sentence because the rapper is "unrepentant" in the sentencing recommendation filed Tuesday.

"Incredibly, while the defendant conceded his acts of violence and abuse throughout trial, he now argues that his victims should shoulder the blame," the filing read.

Diddy's legal team proposed a 14-month sentence ahead of his Oct. 3 hearing for federal charges of transportation to engage in prostitution. The "I Need A Girl" rapper has already spent 13 months behind bars.

Combs' lawyers claimed the musician had been "sufficiently punished" for his crimes.

"Mr. Combs has suffered physically and mentally, and continued incarceration serves no positive goal. Courts do not simply punish, but must restore and rehabilitate with a goal to returning the convicted person to their community as soon as practicable," the sentencing memorandum, obtained by Fox News Digital, stated. "Upon release, Mr. Combs fully intends to abide by every order of this Court and to renew and repair relationships that have been damaged, in a healthy, positive, and lawful manner. After embarking on this journey, Mr. Combs will devote attention to his family and community and to creating new initiatives and opportunities for others."

Diddy's ex-girlfriend, Cassie Ventura, along with other witnesses who testified during the eight-week trial, submitted letters to the judge ahead of the rapper's sentencing.

Ventura told the judge she worries Diddy or one of his associates will come after her with "swift retribution" once released.

"I still have nightmares and flashbacks on a regular, everyday basis, and continue to require psychological care to cope with my past," Ventura, who dated Diddy until 2018, wrote in the letter, obtained by Fox News Digital. "My worries that Sean Combs or his associates will come after me and my family is my reality. I have in fact moved my family out of the New York area and am keeping as private and quiet as I possibly can because I am so scared that if he walks free, his first actions will be swift retribution towards me and others who spoke up about his abuse at trial."
