  • Out of the 14 facial bones, the mandible, maxilla, zygomatic and vomer along with the frontal bone are the primary bones of the skull.
  • The rib cage comprises of 12 pairs of ribs connected to the sternum, the main bone that anchors the rib cage, through the costal cartilage.
  • The ribs numbered 1 to 7 are called true ribs because costal cartilage connects these bones directly to the sternum.
  • The ribs 8 to 12 are classified as false ribs because they are not directly connected to the sternum.
  • The last two ribs 11 and 12 are called floating ribs because they do not connect to the sternum at all.

During glacial maxima, australia, new guinea, and tasmania were a single land mass called?
Over [174]

During glacial maxima, Australia, new guinea, and Tasmania were a single land mass called Sahul.

  • The single Pleistocene continent known as Sahul united Australia with New Guinea and Tasmania. Rising sea levels gave rise to the distinct landmasses that we can now recognize, even though the sea level at the time was up to 150 meters (490 feet) lower than it is now.
  • Australia, New Guinea, Tasmania, and Seram were all parts of the ancient continent Sahul.
  • Since the Last Glacial Maximum, sea levels have risen. Around 18,000 years ago, Sahul began to be partially submerged. Sea levels kept rising until roughly 5000 BCE.
  • After leaving Africa, early human migrations began in Sahul and Sunda. According to recent study, hundreds of individuals traveled in groups on bamboo rafts and eventually settled on Sahul.

Westkost [7]
The most logical answer that I can think from Darwin's Theory of Evolution is that that species had been isolated from other possible panthers to mate with. So after generations of that isolated group of panthers their offspring would eventually become increasingly similar.
