The observations that supported their conclusions include;  Bird wing butterflies were found throughout the Malay archipelago, but species differed slightly from island to island.
Bird families clustered geographically: cockatoos in the Malay Archipelago and Australia, macaws and hummingbirds in the America.
Mockingbirds from different Galapagos islands had Subtle, consistent differences.Tortoise from different Galapagos islands have distinct shells 
The bony shells of armadillos resembled fossilized shells from the extinct Glyptodon.
The fossilized remains of giant sloths were similar to the smaller, living sloths Darwin encountered. Therefore, the resemblance between species and the variations among distant species led to both Darwin and Wallace to conclude that species change over time.

Answer:

Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are perhaps the most important molecules in cell biology, responsible for the storage and reading of genetic information that underpins all life. They are both linear polymers, consisting of sugars, phosphates and bases, but there are some key differences which separate the two1. These distinctions enable the two molecules to work together and fulfil their essential roles. Here, we look at 5 key differences between DNA and RNA. Before we delve into the differences, we take a look at these two nucleic acids side-by-side.

Which individuals in the pedigree are identified and labeled carriers for red-green color blindness? Lisa and Monica Sam, Tim, B
marishachu [46]
<h2><u>Answer:</u></h2>

Sam, Tim, Bella and Joshua on the grounds that the red in Lisa is the partial blindness and they're the main individuals with the full shading red shaded.  

<h3><u> Explanation:</u></h3>

Red green visual impairment is a x connected characteristic, which implies that it is found on the X chromosome. X connected attributes are frequently latent, and this is the reason they for the most part appear in guys, for example, the instance of red green colorblindness.

 A male has just a single duplicate of the X chromosome, so if a passive x connected characteristic is available, he doesn't have the alternative of the prevailing rendition of the quality to appear.

A latent X connected attribute can introduce itself in a female, yet since she has two X chromosomes, she would need two duplicates of the passive quality for it to introduce itself.

This is the reason visual impairment is less normal, yet at the same time conceivable in females. I trust this encourages you with your family.
