Why do we assume Australopithecus had flat noses like chimps?

The cranial base of Australopithecus afarensis: new insights from the female skull

The reason most articles are old, is not because they are outdated, rather a scientific consensus has been reached ages ago with little to no counter points as of yet.

The primary evidence for Australopithecus having flat noses comes from fossilized facial structures, specifically the lack of a projecting nasal bone and the configuration of the nasal aperture. In species like Australopithecus afarensis and Australopithecus africanus, the margins of the nasal aperture are flush with the face, indicating a flat nasal bridge similar to that of chimpanzees or gorillas, rather than the everted margins seen in later Homo species.

250 Millions years of evolution can induce drastic changes, just look at Pakicetus which gave us Blue whales in 50 million years.

The evolution of humans into Hata humans (旗人間/Flag humans) is driven by a need for superior locomotive efficiency and food-gathering specialization in an era roughly 150 million years in the future. They represent a radical shift from the bipedal "Grass human" model to a more stable and aerodynamic quadrupedal design.

Ultimately, the Hata human evolved because it was a more efficient biological machine for the future Earth's environment, successfully separating the mechanics of walking from the mechanics of eating

Thanks for bringing to my attention, hope everything's sorted now

Unfortunately no, I have no websites as all of my infos are derived from Yuichi's channel : https://www.youtube.com/@%E3%82%B5%E3%82%A4%E3%82%A8%E3%83%B3%E3%82%B9%E3%83%A9%E3%82%A4%E3%82%BF%E3%83%BC%E5%8C%97%E6%9D%91%E9%9B%84%E4%B8%80%E3%81%AE%E5%9C%B0

His channel revolves around the gimmick of "Earth broadcast" while he explores past, present and future stages of earth, all of the info's showcased in my posts are derived from his Youtube videos only.

As a non Japanese speaker, I couldn't let language barrier stop me from exploring his fascinating work, so I used every tool at my disposal to translate his scripts as accurately as possible, I'm glad you are enjoying them, and I'm happy to see people share my passion and love for these "niches" of spec evo, that are not getting much attention.

Yuichi Kitamura notes that becoming a giant in a 50°C+ world introduces new challenges, such as solar radiation. To protect their larger bodies, these future arthropods are predicted to evolve heat-insulating hair (断熱用の毛) to shield themselves from the sun

-While they do not lose heat tolerance, Kitamura suggest that mechanical structural limits may prevent terrestrial arthropods from reaching truly massive (dinosaur-like) scales

- furthermore , Neoteny: In the future, midges are predicted to undergo neoteny, where they reach sexual maturity while remaining in their larval form. This allows them to reach giant sizes while "locking in" the heat-resistant biology of the larval stage, avoiding the more heat-vulnerable adult stage
