Answer:

Vestigiality is the retention during the process of evolution of genetically determined structures or attributes that have lost some or all of their ancestral function in a given species. Assessment of the vestigiality must generally rely on comparison with homologous features in related species

Who was the first to recognize the role of the environment as a significant factor in evolutionary change?
faust18 [17]

Answer:

Option A, Jean-Baptiste Lamarck

Explanation:

Options

a. Jean-Baptiste Lamarck

b. Georges Cuvier

c. Thomas Malthus

d. Charles Darwin

e. Charles Lyell

Solution

The second law of Lamarck stated that all living organism eventually adapt to the environment in which they live. However, such adaptations are continuous thereby leading to evolution of species gradually over a long period of time. Lamarck published his theory of evolution in 1801, while Darwin published his book on “origin of species in 1859.  

The result predicted by Lamarck regarding impact of environment on evolution was further supported by Darwin, and future scientist.  

Hence, option A is correct

g What are the three basic assumptions of Darwinian evolution? Group of answer choices Presence of phenotypic variation, some ph
enot [183]

Answer:

1- Presence of phenotypic variation

2- some phenotypic variation due to genetic variation

3- the given trait has an impact on fitness  

Explanation:

The evolutionary theory by natural selection proposed by Darwin in his publication “On the origin of species” (1859) is based on a series of assumptions that enable to understand the amazing biodiversity on the Earth. First, individuals are not identical among them, i.e., there exists variation in the traits among the members of a given population, species, etc. Second, phenotypic variation leads to differential survival and reproduction of the organisms that are best fitted to the environment (i.e., competence among the members of the population). Finally, phenotypic traits are passed from generation to generation (i.e., phenotypic variation is inheritable), thereby favoring offspring from parents more adapted to the environment.
