The continuous, low-level extinction of species is referred to as ___ extinction.
Mice21 [21]

The continuous, low-level extinction of species is referred to as mass extinction.

  • A widespread and quick decline in the diversity of life on Earth is known as an extinction event.
  • A sudden shift in the diversity and abundance of multicellular creatures serves as a telltale sign of such an occurrence. It happens when the rate of diversification outpaces the rate of extinction.
  • A mass extinction event occurs when a species disappears far more quickly than it is replaced.
  • This is typically understood as the loss of almost 75% of all species over a "short" period of geological time, or fewer than 2.8 million years.
  • The Cretaceous-Paleogene extinction, sometimes known as the day the dinosaurs died, is the most well-known of all the mass extinction events.

Feliz [49]

Answer:

Synapsids have a temporary fossa in the lower part of the temporal bone. These reptiles mamiferoides only have a single inferior temporal fenestra.

The synapsids were the first amniots to diversify and appeared  in the middle of the Carboniferous. These first synapses were characterized by the presence of a single temporary fenestra behind each orbit, through which the mandibular muscles pass.
