The answer to this question is: <span>entire ecosystems are being destroyed
In order to achieve a new species, current species have to survive for thousands of years and develop new and better features over that time in order to make it easier for them to adapt.
But our environmental condition today is really worrisome due many irresponsible destruction that is made in the name of profit, which endanger a lot of species</span>
Hope this helps! I added a second cladogram to help with any confusion because I can see how you got stuck with the first one :)
The answer is <em>stratosphere.</em>
This would make it hard for a person to digest their food because enzymes are used to help speed up the process of its specific job
Question 1: Why examining dna is better ?
Examining DNA has a greater interest than examining physical traits because it can determine the genotype of the individual and what are the two alleles that he possesses while examining its physical traits only gives us the phenotype of the individual, which has a lower value than the genotype.
Question 2:
DNA testing is more expensive than examining physical traits, so that in most cases physical features are used to study trait transmission.
There is one case where the determination of the physical trait is sufficient to determine the genotype of the individual: this is when studying codominant alleles such as ABO grouping.
