Which of the following observations best supports the conclusion that two animal species evolved from a common ancestor in recent geological history? *

A. The species are both herbivores.
B. The species have similar bone structure.
C. The species live in the same environment.
D. The species both obtain oxygen from the air.

Answer:

I think its B) The species have a similar bone structure

Explanation:

Answer:

The correct answer to this question is B. The species have similar bone structure.

Explanation:

In biology, homology is the similar structure, physiology, or development of various species of organisms based on their ancestry from the same evolutionary ancestor. An analogy, on the other hand, is a functional similarity of structure that is based not on shared evolutionary origins but rather on simple similarity of use. Homology is contrasted with analogy.

As a result, mammals with vastly different forelimbs, such as humans, bats, and deer, are homologous, Adaptive changes to the forelimb structure of their common early mammalian ancestors are represented by the nearly identical construction and number of bones in these diverse limbs. Similar to structures, then again, can be addressed by the wings of birds and of bugs, Both kinds of organisms use the structures for flight, but they didn't have a common ancestor at the start of their evolutionary development. Sir Richard Owen, a British biologist who lived in the 19th century, was the first to precisely define homology and analogy.

Serially homologous organisms are those whose structures are fundamentally similar to one another but have been altered to carry out distinct functions. The flipper of a whale and the wing of a bat are two examples of this. Both evolved from the forelimbs of their earliest mammalian ancestors, but they have evolved in distinct ways to perform the vastly distinct functions of flying and swimming, respectively. Some of the time it is hazy whether similitudes in structure in various creatures are similar to or homologous.

1.What factor increases the likelihood of a landslide occurring?
A.lots of water
B.forest fire
C.all of the above
D.over steepening of a hill

2. Are landslides be considered a fast or slow geological process?
A. Slow, because it takes all winter for the snow to build up.
B. Slow, because all of the snow has to melt before a landslide can happen.
C. Fast, because rain falls fast.
D. Fast because conditions for landslides happen within months, slow processes can take millions of years.

B. The canyon was covered by the ocean and the water receded (went down).
C. It is still part of the ocean, that’s why there are marine animals there.
D. All of the fossils came from things that lived in the Colorado River.

4. Why does the Grand Canyon have layers?
A. The uplift of the land caused layers.
B. Deposition of sediments over millions of years.
C. Erosion by wind has worn away sedimentary rock.
D. Erosion by the Colorado River has formed layers.
