29. How did Thomas Malthus contribute to Charles Darwin's insights about natural selection? Group of answer choices Malthus proposed that populations tend to grow faster than resources do. Malthus was among the first to recognize that the fossil record documents species changing over time. Malthus was the one who proposed the idea of gradualism. Malthus developed the first system of categorizing and naming species. Malthus proposed that characteristics acquired during one's lifetime can be passed to offspring.
Ton are the same thing. 4. According to the theory of natural selection, why are some individuals more likely than others to survive and reproduce? a. They pass on to their offspring new characteristics they acquired during their lifetimes. b. They are better adapted to exist in their environment than others. c. They do not pass on to their offspring new characteristics they have acquired during their lifetimes. d. They tend to produce fewer offspring than do others in the same environment.

Which can bring new traits to a population and why? 1. natural selection - because it increases the frequency of adaptive alleles in a population over time 2. natural selection and mutation because both increase the frequency of adaptive alleles in a population over time 3. mutation - because it increases the frequency of adaptive alleles in a population over time 4. natural selection and mutation because both make new alleles 5. natural selection - because it makes new alleles 6. mutation - because it makes new alleles
1. Definitions of phenotype, genotype, allele, gene, microevolution, macroevolution 2. Know that in humans, most of the genetic variation is observed within populations, and know why that is. 3. Know the 4 processes of evolution (3 neutral + natural selection) 4. Know that evolution isn't progressive and doesn't necessarily lead to more complexity 5. Know that evolution can lead to traits that decrease survival (ex: sexual selection)
. The Process of Evolution by Natural Selection – Be able to explain the process of evolution by natural selection as it applies to a specific living thing using the outline below: Natural variations caused by random mutations (adaptations) in DNA exist within populations. Those with helpful adaptations survive an environmental change (maybe a predator.) The survivors breed, passing on the inherited mutation (adaptation) to offspring. The resulting population has more of the successful inherited mutation (adaptation) than the original population. Phylogenetic Trees Infer evolutionary relationships of living things by interpreting phylogenetic trees. Know the divisions of hierarchical classification. (DKPCOFGS) c. Differentiate between homologous and analogous (caused by convergent evolution) structures
