What evolutionary advantages might arise from not needing free water for fertilization?
You would not become so desperate when a drought occurred. It would be easier to farm if water was not such a necessity.
What evolutionary development do scientists think occurred in the Cambrian period that gave rise to more complex fish?
They theorize that during this period the first of three gill arches on a jawless fish evolved into the first jaws.
Which is NOT a sign that a double displacement reaction has occurred?
1) Formation of a precipitate 2) Usually there is a colour change. 3)Neutralization reactions (also a double displ. reaction) involving an acid and a base form water which is a clue.
The most direct evidence that evolution has occurred comes from what?
Bacteria because they reproduce every 20 minuites which is fast enough so scientist can see them evolve over time. or Viruses, they evolve, that's why we have to constantly change are vacines.

What order are triassic Jurassic Cambrian devonian?

What was the period before the carboniferous period?
The period before the Carboniferous period is known as the Devonian period, which lasted from approximately 419 to 359 million years ago. During the Devonian, often referred to as the "Age of Fishes," diverse marine life flourished, and significant evolutionary advancements occurred, including the emergence of early land plants and amphibians. This period set the stage for the extensive terrestrial ecosystems that would develop in the Carboniferous.
How long ago was the Devonian Period?
The Devonian Period lasted from about 395 to 345 million years ago. It is part of the Paleozoic Era.
What occurred prior to angiosperms?

Which era is the Devonian era?
The Devonian era is a geological period that occurred approximately 419 million to 359 million years ago. It is known for the diversification of marine life, including the appearance of early fish and amphibians, as well as the spread of forests on land.

Where do devonian live?
The Devonian period is a geologic time period that occurred approximately 419 to 359 million years ago. During this time, life existed in various forms, including fish, plants, and invertebrates. The organisms living during the Devonian period inhabited environments such as oceans, rivers, and landmasses that are now part of present-day continents.
