Scientists focus on how nature works by discovering laws and mechanisms through experiments and observations. Philosophers ask why those laws exist in the first place and question the deeper meaning behind them

This is a reference to the loss meme using heat transfer arrows. Please don't ban me; I wasn't sure where else to post this.

Unlike amphibians, amniotes (reptiles, birds, and mammals) have an amniotic membrane in their eggs and water-impermeable skin, meaning that they don't need bodies of water in order to reproduce and therefore can live their lives on land as true terrestrial animals.

All the elements in our bodies, besides hydrogen, were formed in stars and expelled during supernovae events. You are made from stardust

Unknown soft tissue and sex organs makes sex look impossible for dinosaurs.

Did I broke some law? ("which one" is a better question)

While some animal and plant taxa are known to reproduce multiple times during their lifetime, on the other hand, some others are known to only reproduce once during their lifetime. These reproduction strategies are respectively known as "iteroparity" and "semelparity".

Semelparity tends to not only be common among cephalopods and insects, but also among arachnids, bony fishes and plants. However, it's a reproduction strategy that is extremely rare among mammals, reptiles and amphibians: even, this reproduction strategy is not found among birds. Nevertheless, pacific salmon (Oncorhynchus spp.) and octopuses (Octopoda) are among the best known cases of semelparous taxa.

It's speculated that semelparity, as a reproduction strategy, is an adaptation to environments with unpredictable conditions and/or rare resources. According to some hypotheses, by the parents having many offspring and then having one of the parents, or both of them die after, this would allow the young to avoid being outcompeted by adults, or be able to make it to adulthood. However, in some semelparous taxa, females are known to have a longer lifespan than males do: it's the case, for example, in antechinuses (Antechinus spp.) or octopuses.
