Explica como crees que se originó la vida sobre el planeta tierra
aleksandr82 [10.1K]
Sabemos que la vida comenzó hace al menos 3.500 millones de años, porque esa es la edad de las rocas más antiguas con evidencia fósil de vida en la tierra. Estas rocas son raras porque los procesos geológicos posteriores han remodelado la superficie de nuestro planeta, a menudo destruyendo rocas más viejas y creando otras nuevas (lo siento si es un amor incorrecto, marque como más inteligente si es correcto).

What affects do islands have on animal size
Sever21 [200]

There's two effects that the islands have on the size of the animals, reducing of size, or increasing of size. The reducing of size is known as island dwarfism, while the increase in size is known island gigantism.

The effect of the island environment effects different types of animals in different manner, and it also has to be taken in account the size of the island. In general, the small animals tend to increase their size on the islands, while the large animals tend to decrease in size. The reason for this is that the smaller animals, because of the isolation, usually lack predators or they are very few, but also have sufficient amounts of food, thus they grow in size. The larger animals though, decrease their size because there isn't enough food on the islands to support them, thus with the decrease in size they consume less. Also, since they usually lack predators, they do not have to be large in order to defend themselves.
