If you can answer this correctly I'll give you brainliest. Thanks!

A student draws this model to show how humans evolved from ancestral primates. What are the pros and cons of this model in regard to the theory of evolution? Explain how you’d make it more accurate. To create a scientifically credible answer, use a credible website to research human evolution.

Answer 1

An appreciation of the fundamental principles of evolutionary biology provides new insights into major diseases and enables an integrated understanding of human biology and medicine. However, there is a lack of awareness of their importance amongst physicians, medical researchers, and educators, all of whom tend to focus on the mechanistic (proximate) basis for disease, excluding consideration of evolutionary (ultimate) reasons. The key principles of evolutionary medicine are that selection acts on fitness, not health or longevity; that our evolutionary history does not cause disease, but rather impacts on our risk of disease in particular environments; and that we are now living in novel environments compared to those in which we evolved. We consider these evolutionary principles in conjunction with population genetics and describe several pathways by which evolutionary processes can affect disease risk. These perspectives provide a more cohesive framework for gaining insights into the determinants of health and disease. Coupled with complementary insights offered Coupled with complementary insights offered by advances in genomic, epigenetic, and developmental biology research, evolutionary perspectives offer an important addition to understanding disease. Further, there are a number of aspects of evolutionary medicine that can add considerably to studies in other domains of contemporary evolutionary studies.

Answer 2

Explanation:

Osmosis is a type of simple diffusion in which water molecules diffuse through a selectively permeable membrane from areas of high water concentration to areas of lower water concentration.Photophosphorylation: It is the process where the phosphorylation of adenosine diphosphate to ATP occurs in the presence of sunlight, and it is the process that occurs in plants during photosynthesis, where glucose produced in the process of photosynthesis undergoes metabolism and releases the energy, where It is ...
