Answer:
Study of comparative anatomy emerged in the 18th century and led to establishment of relationship between species based on the common traits
Explanation:
The three major events that occurred after this discovery are –
a) Discovery of the fact that the age of earth is much higher than the age of earth as found in previous theories of continental drift theory
b) The age of the oldest fossils was determined and based on that relative age of all species (as found in fossils) was determined.
c) The determination of age of fossil helped to find the gaps in the evolutionary tree and hence provoked search of these missing species.
The study of comparative anatomy started somewhere around 1800 when George Cuvier emerged as father of comparative anatomy
Based on comparative anatomy study, scientists such as Buffon and Lamarck worked on establishing relationship between species based on the common traits shared between them
Answer:
ummmmmm??? oooooook??????
Here is the complete statement:
The black footed ferret specie can be saved by the ENDANGERED SPECIES ACT. The US FISH AND WILDLIFE SERVICES will manage the Act.
EXPLANATION:
An endangered specie refers to an animal or plant species, whose population has become very low and is in danger of becoming extinct in the nearest future. In the United States of America, such plants and animals are usually managed by the Us Fish and Wildlife services. This is a federal agency that is responsible for the management of different forms of wildlife, fish and natural habitats within the US.
The Endangered Specie Act is a US law that makes provisions for the management of both plants and species, which are deem to be on the verge of becoming extinct. The law makes provisions for the conservation of endangered living organisms and their natural habitats. The endangered specie Act prohibits the hunting or killing of endangered species; acting contrary to this law usually carry severe penalties.
The answer is directional selection
It is the mode of natural selection in which a single phenotype is favored, causing the allele frequency to continuously shift in one direction. The advantageous allele increases in frequency independently of its dominance relative to other alleles; that is even if the advantageous allele is recessive, it will eventually become fixed, changes the average value of a trait. Occurs most often under environmental changes and when populations migrate to new areas with different environmental pressures.
