The ancestors of gars, horseshoe crabs and coelacanths looked almost the same as their modern relatives. Darwin called species like these “living fossils'' because they seem like they are evolutionarily frozen in time. But Darwin was wrong.

Who will win? Jasper from @Minutelabsio or Asa Stahl from @planetarysociety ?
They say you eat with your eyes first. And they (whoever 'they' are) seem to be right. Would you eat a poop-shaped treat or do you save things like that for Halloween?

Dogs are great companions, AND having them around reduces the chance of developing allergies
The animals we eat generally don't eat other animals - why is that?
Petri dishes are filled with nutrient agar and used as food for bacteria - but only a few species will actually grow on them. And if we can't grow them, then we can't study them either.
