The process of biological evolution has produced species thatare better adapted to their environments.C. When an animal is better adapted to its environment, the process of natural selection makes it more likely that the animalwill reproduce.

Evolutionary biologists often say that evolution “selects for outcomes” not for the particular genetic changes that lead to that adaptive outcome. Given that perspective, is it surprising that different gene mutations might be involved in the evolution of the same trait (such as light skin or adaptation to living in high mountains)? Why or why not?
While the French biologist LaMarck was correct in proposing that evolution does occur, he believed that the long necks of giraffes evolved as generations of giraffes reached for ever higher leaves on the trees. Using these observations, LaMarck proposed the theory that evolution occurs due to the inheritance of characteristics acquired during an organism’s lifetime. From what you know about the scientific method, why is this incorrect?
Jean-Baptiste Lamarck was one of the first scientists to propose a method for evolutionary change. He suggested that an organism's body would adapt to its surrounding based upon the use or disuse of certain body parts. Why was this a mistaken idea? a As species become distinctly different from each other, so do their body forms, which is a result of their genes changing. b Individuals adapt and change, not populations. c Evolutionary change can only act upon traits that are inheritable, not traits that are acquired through an organism's lifetime. d When an organism migrates to a new environment or the environment it currently lives in changes, the organism must adapt, or it will not survive.
Why was Jean Baptiste Lamarck wrong about the mechanism of evolution? A. Because giraffes haven't evolved in billions of years. B. Because individuals do not pass on any traits that they acquire during their lifetime. C. Because individuals can change their traits during their lifetime and pass on those traits to their offpsring. D. Because he misunderstood the structure of DNA.
Which of the following statements about evolution is false?a. Gene mutations alone amount to evolution. b. Genetic drift and gene flow are modern theories of evolution.c. Natural selection contributes to evolution.d. Chimpanzees evolved from a hominoid ancestor.
Which of the following is NOT true of biological evolution? a. It always involves genetic changes b. it always involves groups of individuals c. it requires the existence of genetic variation within a population d. it can include non-genetic changes in an organism, if the organism is complex enough
Generally, will natural selection result in an increase or decrease in variation? Why does this happen, and how, in theory, will it affect evolution in the future?
EVOLUTION LINK Write short paragraphs explaining each of the following statements: (a) Natural selection chooses from among the individuals in a population those most suited to current environmental conditions. It does not guarantee survival under future conditions. (b) Individuals do not evolve, but populations do. (c) The organisms that exist today do so because their ancestors had traits that allowed them and their offspring to thrive. (d) At the molecular level, evolution can take place by the replacement of one nucleotide by another. (e) Evolution is said to have occurred within a population when measurable genetic changes are detected.
Which of the following is not true of natural selection? (a) natural selection acts to preserve favorable traits and eliminate unfavorable traits (b) the offspring of individuals that are better adapted to the environment will make up a larger proportion of the next generation (c) natural selection directs the course of evolution by preserving the traits acquired during an individuals lifetime (d) natural selection acts on a populations genetic variability, which arises through mutation (e) natural selection may result in changes in allele frequencies in a population
. The upper forelimbs of humans and bats have fairly similarskeletal structures, whereas the corresponding bones inwhales have very different shapes and proportions. However,genetic data suggest that all three kinds of organisms divergedfrom a common ancestor at about the same time. Which ofthe following is the most likely explanation for these data?(A) Forelimb evolution was adaptive in people and bats, butnot in whales.(B) Natural selection in an aquatic environment resulted insignificant changes to whale forelimb anatomy.(C) Genes mutate faster in whales than in humans or bats.(D) Whales are not properly classified as mammals.
Relative to a human lifetime, is evolution a process too slow or too fast for us to see it easily?
What does the term evolution mean? A. The characteristics of species become more complex over time. B. The strongest individuals produce the most offspring. C. The characteristics of an individual change through the course of its life, in response to natural selection. D. The characteristics of populations change through time.
