  • Divergent Evolution in Antiherbivore Defences Within Species Complexes at a Single Amazonian Site

Classic theory in plant–insect interactions has linked herbivore pressure with diversification in plant species. We hypothesize that herbivores may exert divergent selection on defences, such that closely related plant species will be more different in defensive than in non-defensive traits. 2. We evaluated this hypothesis by investigating two clades of closely related plant species coexis- ting at a single site in the Peruvian Amazon: Inga capitata Desv. and Inga heterophylla Willd. spe- cies complexes. We compared how these lineages differ in the suite of chemical, biotic, phenological and developmental defences as compared to non-defensive traits that are related to habitat use and resource acquisition. We also collected insect herbivores feeding on the plants. 3. Our data show that sister lineages within both species complexes are more divergent in antiherbi- vore defences than in other non-defensive, functional traits. Moreover, the assemblages of herbivore communities are dissimilar between the populations of coexisting I. capitata lineages. 4. Synthesis. Our results are consistent with the idea that for the I.

  • The Genetic Causes of Convergent Evolution
    Nature Reviews Genetics | AOP, published online 9 October 2013; doi:10.1038/nrg3483 REVIEWS The genetic causes of convergent evolution David L. Stern Abstract | The evolution of phenotypic similarities between species, known as convergence, illustrates that populations can respond predictably to ecological challenges. Convergence often results from similar genetic changes, which can emerge in two ways: the evolution of similar or identical mutations in independent lineages, which is termed parallel evolution; and the evolution in independent lineages of alleles that are shared among populations, which I call collateral genetic evolution. Evidence for parallel and collateral evolution has been found in many taxa, and an emerging hypothesis is that they result from the fact that mutations in some genetic targets minimize pleiotropic effects while simultaneously maximizing adaptation. If this proves correct, then the molecular changes underlying adaptation might be more predictable than has been appreciated previously.

  • The Evolution of Mammalian Aging

While all studied mammals express a well-de®ned aging phenotype, many amphibians and reptiles fail to show signs of aging. In addition, mammalian species show great similarities in their aging phenotype, suggesting that a common origin might be at work. The proposed hypothesis is that mammalian aging evolved together with the ancestry of modern mammals. In turn, this suggests that the fundamental cause of human aging is common to most, if not all, mammals and might be a unique phenom- enon. Experimental procedures capable of testing these theories and how to map the causes of mammalian and thus, human aging, are predicted. q 2002 Elsevier Science Inc. All rights reserved.

Evidence of Evolution & the Week 5 Remote Learning Mechanisms of Biodiversity Natural Selection The total variety of all the organisms in the biosphere= Biodiversity Where did all these different organisms come from? How are they related? Some organisms in a population are less likely to survive. Over time, natural selection results in changes in the inherited characteristics of a population. WHAT IS DARWIN’S THEORY? These changes increase a species’ fitness in its environment. Any inherited characteristic Ability of an individual to that increases an organism’s survive and reproduce in its chance of survival= specific environment= FITNESS ADAPTATION WHAT IS DARWIN’S THEORY? STRUGGLE FOR EXISTENCE: means that members of each species must compete for food, space, and other resources. SURVIVAL OF THE FITTEST: organisms which are better adapted to the environment will survive and reproduce, passing on their genes. DESCENT WITH MODIFICATION: suggests that each species has decended, with changes, from other species over time. • This idea suggests that all living species are related to each other, and that all species, living and extinct,share a common ancestor.

  • Evolutionary Origins for Ecological Patterns in Space PERSPECTIVE Mark C
    PERSPECTIVE Evolutionary origins for ecological patterns in space PERSPECTIVE Mark C. Urbana,b,1, Sharon Y. Straussc, Fanie Pelletierd, Eric P. Palkovacse, Mathew A. Leiboldf, Andrew P. Hendryg,h, Luc De Meesteri,j,k, Stephanie M. Carlsonl, Amy L. Angertm, and Sean T. Gierya,n Edited by Simon A. Levin, Princeton University, Princeton, NJ, and approved June 5, 2020 (received for review January 24, 2020) Historically, many biologists assumed that evolution and ecology acted independently because evolution occurred over distances too great to influence most ecological patterns. Today, evidence indicates that evolution can operate over a range of spatial scales, including fine spatial scales. Thus, evolutionary divergence across space might frequently interact with the mechanisms that also determine spatial ecological patterns. Here, we synthesize insights from 500 eco-evolutionary studies and develop a predictive framework that seeks to understand whether and when evolution amplifies, dampens, or creates ecological patterns. We demonstrate that local adaptation can alter everything from spatial variation in population abundances to ecosystem properties. We uncover 14 mechanisms that can mediate the outcome of evolution on spatial ecological patterns. Sometimes, evolution amplifies environmental variation, especially when selection enhances resource uptake or patch selection. The local evolution of foundation or keystone species can create ecological patterns where none existed originally. However, most often, we find that evolution dampens existing environmental gradients, because local adaptation evens out fitness across environments and thus counteracts the variation in associated ecological patterns. Consequently, evolution generally smooths out the underlying heterogeneity in nature, making the world appear less ragged than it would be in the absence of evolution.

  • Evolution Lesson 8.4: Macroevolution and the Origin of Species Lesson
    Chapter 8: Evolution Lesson 8.4: Macroevolution and the Origin of Species Fast or slow? Which is better, the direct route or the scenic route? Each has its advantages, depending on the situation. And that describes evolution. It can be fast or slow, depending on the situation. Lesson Objectives • Describe two ways that new species may originate. • Differentiate between allopatric, peripatric, parapatric, and sympatric speciation. • Identify the different patterns of macroevolution • Distinguish between gradualism and punctuated equilibrium. • Understand the concept of extinction and how it affects evolution. Vocabulary • allopatric speciation • behavioral isolation • coevolution • convergent evolution • divergent evolution • geographic isolation • gradualism • parapatric speciation • peripatric speciation • punctuated equilibrium • speciation • sympatric speciation • temporal isolation Introduction Macroevolution is evolution over geologic time above the level of the species. One of the main topics in macroevolution is how new species arise. The process by which a new species evolves is called speciation. How does speciation occur? How does one species evolve into two or more new species? 275 Origin of Species To understand how a new species forms, it’s important to review what a species is. A species is a group of organisms that can breed and produce fertile offspring together in nature. For a new species to arise, some members of a species must become reproductively isolated from the rest of the species. This means they can no longer interbreed with other members of the species. How does this happen? Usually they become geographically isolated first. The macroevolution of a species happens as a result of speciation. Speciation is the branching off of individuals from the species they originally were.

  • Divergent Evolution and Evolution by the Birth-And-Death Process in the Immunoglobulin VH Gene Family
    Divergent Evolution and Evolution by the Birth-and-Death Process in the Immunoglobulin VH Gene Family Tatsuya Ota and Masatoshi Nei Department of Biology and Institute of Molecular Evolutionary Genetics, The Pennsylvania State University Immunoglobulin diversity is generated primarily by the heavy- and light-chain variable-region gene families. To understand the pattern of long-term evolution of the heavy-chain variable-region (V,) gene family, which is composed of a large number of member genes, the evolutionary relationships of representative Vn genes from diverse organisms of vertebrates were studied by constructing a phylogenetic tree. This tree indicates that the vertebrate Vn genes can be classified into group A, B, C, D, and E genes. All Vn genes from cartilaginous fishes such as sharks and skates form a monophyletic group and belong to group E, whereas group D consists of bony- fish Vn genes. By contrast, group C includes not only some fish genes but also amphibian, reptile, bird, and mammalian genes. Group A and B genes were composed of the genes from mammals and amphibians. The phylogenetic analysis also suggests that mammalian Vu genes are classified into three clusters-i.e., mammalian clans I, II, and III-and that these clans have coexisted in the genome for >400 Myr. To study the short-term evolution of Vn genes, the phylogenetic analysis of human group A (clan I) and C (clan III) genes was also conducted. The results obtained show that Vn pseudogenes have evolved much faster than functional genes and that they have branched off from various functional Vu genes.
