Recent research has found that on one island of the Galapagos two finch species interbred. This interbreeding may have resulted

in a hybrid species that ultimately led to the extinction of one of the species Darwin discovered. They call this speciation in reverse, or despeciation. Based on what you know about speciation, why are these terms appropriate?

Answer:

Speciation is the method by which unique species evolve from a common ancestor. In this case, two of these species that split from a common ancestor interbred and created a hybrid. This hybrid was apparently stronger and possibly better adapted to the environment, which led to extinction of a species formed by the initial speciation event.

Which sentences in the passage directly involve the geosphere?
liraira [26]

Answer: 1. Maury digs a hole in the ground with a shovel and plants a sunflower seed.

2. In time, the sunflower draws water and nutrients from the soil and releases water vapor into the air through its leaves.

3.  The air also brings rainwater to the soil.

Geosphere refers to the crust and upper mental part of the earth. It represents the solid part of the earth. The following sentences in the passage directly involve the geosphere.

Maury digs a hole in the ground with a shovel and plants a sunflower seed.: Here, the ground is the part of the geosphere being impacted by the shovel to dig a hole.

In time, the sunflower draws water and nutrients from the soil and releases water vapor into the air through its leaves.: Here, the water present in the geosphere is being taken up by plants. Therefore, this sentence involves geosphere.

The air also brings rainwater to the soil. : Here, the water being evaporated from geosphere comes back in the form rain to the geosphere.

. It has been observed that organisms on islands are different from, but closely related to, similar forms found on the nearest
MatroZZZ [7]

Answer:

       The right answer to this question is option A) island forms and mainland forms descended from common ancestors.

       It's known in science that a long time ago, all the continents were only one, united all together in a bigger one. This can be observed by the way every continent can fit another one.

       A proof of that too, is evolution, when we find organisms in an island that share some characteristics with organisms from another island, that can mean some things, they come from the same place, or these islands share characteristics that lead these organisms to be this way through evolution.
