Summary Introduction

Introduction: Charles Darwin’s theory of evolution states that all organisms developed and raised from natural selection with some small changes and inherited variation that acquired by the organism to survive, compete, and reproduce.

Answer to Problem 1SQ

Correct answer: d. Parents get new traits through their actions and pass them to offspring.

Explanation of Solution

Reason for the correct answer:

Charles Darwin did not understand physical anthropology, that the biological changes and gene expression over successive years paved the way for evolution and variations among different species.

Option d. is given as “Parents get new traits through their actions and pass them to offspring”.

Hence, the correct answer is option d.

Reasons for incorrect answers:

Option a. is given as “Earth is very old, and its past organisms are preserved as fossils”.

The statement of Darwin is true that ancestral organisms are preserved as fossils that gave the idea of the theory of evolution. Therefore, option a is incorrect.

Option b. is given as “physically similar organisms tend to be closely related”.

The statement of Darwin is true; the interrelated species are evolved from a common ancestor. Therefore, option b is incorrect.

Option c. is given as “organisms compete for limited resources to survive to reproduce”.

The statement of Darwin is true, in the natural selection of evolution, the organism that survived and competed become the survival of the fittest. Therefore, option c is incorrect.

Hence, options a., b., and c. are incorrect.

Conclusion

Charles Darwin was not able to state that the gene expression and environmental factors are the key cause of evolution.

Preoperative Diagnosis: Torn medial meniscus, left knee Postoperative Diagnosis: Combination horizontal cleavage tear/flap tear, posterior horn, medial meniscus, left knee. Operation: Arthroscopic subtotal medial meniscectomy, left knee Anesthetic: General endotracheal Description of Procedure: The patient was placed on the operating table in the supine position and general endotracheal anesthesia was administered. After an adequate level of anesthesia was achieved, the patient's left lower extremity was prepped with Betadine scrubbing solution, then draped in a sterile manner. Several sites were then infiltrated with 1% Xylocaine solution with Epinephrine to help control bleeding from stab wounds to be made at these sites. These stab wounds were made anterolaterally at the level of the superior pole of the patella for insertion of an irrigation catheter into the suprapatellar pouch area, anterolaterally at the level of the joint line for insertion of the scope and anteromedially at…
