Answer:
embryonic development
Explanation:
other non aquatic vertebrates exhibit gill slits even though they never breathe through gills. These slits are found in the embryos of all vertebrates because they share as common ancestors the fish in which these structures first evolved.
Answer:
The Adaptationist Fallacy can prove very costly to biologist who are assuming it wrong according to the function in the environment. Let us have an example of the phenotype of wheat diploid breed that produces non-bearded grains variety, but we cannot assume it as a beneficial phenotype without further extensive research. After research, we came to know that there is also a major hexaploid bearded variety, that produces more number of grains. That's how, the Adaptationist Fallacy may prove fatal if we have assumed diploid as a major beneficial phenotype.
<h3><u>Answer;</u></h3>
The above statement is <u>False </u>
<h3><u>Explanation;</u></h3>
- Speciation is an evolutionary process in which new species arise. There are three types of speciation, namely; sympatric, parapatric and allopatric speciation.
- <em><u>Sympatric speciation is a pattern in which speciation occurs in the absence of a physical barrier to gene flow; ex. polyploidy arising in flowers.</u></em>
- In an Allopatric speciation on the other hand, a physical barrier arises and separates two populations, ending gene flow between them and allowing reproductive isolating mechanisms to evolve so that later if the two groups come back into contact they will no longer be able to reproduce together, therefore making them different species.
Answer:
A Mutation is when a DNA gene is damaged or changed in a way that changes the genetic message carried by that gene.
Explanation:Mutations are sometimes good and sometimes bad it can also cause genetic variation which increases the survival of a species
