View Available Hint(s) An important challenge to traditional (pre-1860) ideas about species was the observation that seemingly dissimilar organisms, such as hummingbirds, humans, and whales, have similar skeletal structures. This most directly suggested to biologists that __________. these seemingly dissimilar organisms might have evolved from a distant, common ancestor advantageous changes can be passed along to offspring only the best-adapted organisms can survive most evolution occurs rapidly following a mass extinction.

Answer:

these seemingly dissimilar organisms might have evolved from a distant

Explanation:

Evolution deals with history of organism survival on Earth.

The evolutionary biologists makes use of fossils as proves to give light to having a clear view of how species survived in past times.

Before the theory of natural selection by Charles Darwin, Evolutionary Biologists were filled with questions about why the type of skeletal structural specimens collected were equal and different in dissimilar organisms as it does not exhibit the links seen between these species.

The theory of evolution proposed the mechanism of divergent evolution as a solution to these questions.

Therefore, we conclude that "these seemingly dissimilar organisms might have evolved from a distant" is the right answer.

kakasveta [241]
<span>F- allele for freckles
f- </span><span>allele without freckles

1) The man is heterozygote and has freckles, its indicating that the allele for freckles is dominant.
A cross between him and a woman who is also </span><span>heterozygote: Ff x Ff
it would result in the following probabilities:
- 1/4 - homozygote with freckles: FF
- 2/4 - </span><span>heterozygote with freckles: Ff
- 1/4- </span><span>homozygote without freckles:ff

Their son would have a probability of 75% of being born with freckles.


2) The cross resulted in this probabilities:
</span><span><span>- 1/4 - homozygote with freckles: FF
- 2/4 - </span><span>heterozygote with freckles: Ff
- 1/4- </span><span>homozygote without freckles:ff
So, the chance of being born heterozygote for this gene is 2/4, which is the same as half (50%).

Nikitich [7]

Answer:

<h2>Have a common understanding in the classification of organisms</h2>

Explanation:

  • Taxonomy plays an important role in the classification of organisms to study the organisms on the basis of their properties.
  • Taxonomy is a branch of biological science that explains the identification, characterization, naming and classification of the organisms thus it is helpful to understand the different types of organisms that are present in the biosphere.
  • Taxonomy makes the scientist come on one point about the unknown organisms according to morphology, anatomy, physiology and some other properties of the organisms.
  • Thus a common understanding is generated among scientists of the world.
