Ancient 'American Cheetah' Reclassified as Puma Relative With Regional Diets

New DNA and isotopic analyses of Miracinonyx trumani show it wasn't a cheetah but a sister species to the modern puma, with two distinct populations: a northern, pescatarian-adapted group and a southern, more typical carnivore group. The findings extend its known range by about 20 degrees latitude and reveal flexible predation and circadian adaptations, with the lineage declining as climate changed at the end of the last ice age.

DNA Rewrites the 'American Cheetah' as a Puma Relative, Not a Cheetah

New DNA and isotope analyses show Miracinonyx trumani, historically dubbed the American cheetah, was not a cheetah at all but a close relative of the modern puma; cheetah-like features are now seen as convergent evolution, and Arctic Yukon populations adapted to a fish-based diet, expanding the species' range northward into the Arctic. The lineage diverged from pumas about 2.6 million years ago, underscoring remarkable ecological flexibility in this North American predator.

Pumas Quietly Cut Deer-Related Crashes in Washington

Pumas Quietly Cut Deer-Related Crashes in Washington

A study of pumas and deer on Washington's Olympic Peninsula finds higher puma activity correlates with fewer deer-vehicle collisions: deer alter their space and reduce nighttime road use around pumas, lowering crash risk by about 67% and potentially reducing total accidents by up to 76% over five years; the effect comes from scaring deer rather than predation, highlighting a possible ecosystem service of coexistence with large predators and prompting future work to quantify any monetary savings.

Abby Steiner Sues Puma and Mercedes Over Defective Shoes Ending Her Sprint Career

U.S. track star Abby Steiner filed a lawsuit in Middlesex County Superior Court, Massachusetts, against Puma and Mercedes’ Formula 1 team alleging their running shoes with carbon‑fiber plates and nitrofoam are defective and unsafe, causing injuries that ended her sprint career. The suit names models including Deviate Nitro Elite 2 and 3 and evoSpeed Tokyo Nitro, accuses the defendants of negligent design, manufacturing, and failure to warn, and notes Mercedes’ engineering involvement in track spikes. Steiner wore the shoes with the expectation they were safe and seeks damages under multiple counts, including negligence and breach of warranty, with injuries leading to surgeries by 2025.

Anta Sports Bets Big on Puma with 29% Stake in $1.8B Deal

Anta Sports has agreed to acquire a 29.06% stake in Puma SE for about €1.5 billion ($1.8 billion), financed entirely with internal cash, with closing expected by the end of 2026. Anta will seek representation on Puma’s supervisory board while preserving Puma’s brand identity and independence, and it says it currently has no plan to make a takeover offer, though a deeper partnership could be explored in the future.
