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

Below are characteristics of a never-before described plant species recently identified as part of the ‘All Taxa Biodiversity Inventory’ (ATBI). Field Notes: Specimen collected from shaded area along stream in South Cumberland State Park (Grundy County, TN). Laboratory Analysis: Body: Large leaves emerging from underground rhizome. Size: 63 cm Chromosomal Analysis: Plant body is diploid—chromosome number of 44. Lignin test: Positive Cuticle: Present Leaves: Present—large with branched veins. Underside has sori (containing haploid spores). Roots: Present—branch from the inside. Stem: Present—vascular tissue (xylem & phloem) present. Life History: Diploid sporophyte dominant generation. Haploid spores germinate into heart-shaped, haploid, gametophyte. Water required for fertilization; no seed is produced. Diploid zygote develops into sporophyte.
