• VANCOUVER, British Columbia, April 03, 2024 (GLOBE NEWSWIRE) -- Brixton Metals Corporation (TSX-V: BBB, OTCQB: BBBXF) (the “Company” or “Brixton”) is pleased to announce additional results from the ongoing exploration program at the Hog Heaven Project, which is operated by Ivanhoe Electric Inc. under a definitive Earn-in Agreement with Brixton.
• Hog Heaven is an advanced-stage, high-sulphidation, epithermal copper-silver-gold project having historical production with copper porphyry potential.
• The project is located 50 miles southwest of Kalispell, Montana, USA.
• Chairman and CEO Gary R. Thompson stated, “Drilling at the Hog Heaven Project continues to deliver highly encouraging results, specifically the copper enrichment.

• Including more than 350,000 known species, they dominate the ecological system, shape food webs and play a vital role in oxygen production.
• Plus, many of them are valuable commercial crops – think of roses, grains and tomatoes.

• A step change in research is shaking up the way scientists think about plants: they are far more complex and more like us than you might imagine.
• But not all scientists agree it is an angiosperm, due to the different definitions of flower organs.
• This is the largest known amber-preserved fossil flower, measuring about 3cm across and about three times as large as most floral fossils, showing beautiful details of this ancient flower.

Jurassic or Cretaceous?

• The timing of flowers’ evolution is still a matter of debate between scientists, but most scientists are in one of two camps: Jurassic or Cretaceous.
• Analyses using molecular data (DNA or protein sequences) suggest flowers could be much older than the fossil record shows – a Jurassic (145 million years ago) or even Triassic origin (201 million years ago).

Deciphering the past by molecular data

• One technique scientists use to determine the timing of evolutionary events is the “molecular clock”.
• This concept originated from the understanding that genetic mutations tend to accumulate at a constant rate across both time and species.
• To construct a molecular clock, researchers analyse gene segments that have been conserved throughout a species’ evolution.

Piecing the puzzle together

• Scientists examine fossil plants and observe the gradual changes in structures such as leaves, flowers and seeds over time.
• Comparing their anatomy allows researchers to identify similarities and differences between extinct and still-living species, or species in different clades.
• Biological traits which appear similar may be a result of convergent evolution, indicating changes in characteristics for environmental adaptation, rather than genetic similarity.

Mathematical approach can also help

• There is also a mathematical approach to estimating the age of angiosperms – for instance, using the Bayesian Brownian Bridge (BBB) method.
• This statistical model is a scientific formula that uses the distribution of fossils through time to estimate the age of a group.
• By using the BBB method, an international research team found that the origin of angiosperms supports a pre-Cretaceous hypothesis.
