This activity works well as an introductory, This revision/home learning worksheet comes with answers and helps students to understand Speciation in B6 Biology .It tests students on the theory of speciation proposed by Wallace and how populations can be separated by physical barriers which creates different environments and results in the 2 populations evolving differently leading to new species.Whats included? One of the best examples of speciation can be found in our own family tree. Allopatric speciation (allo = other; patric = homeland) involves geographic separation of populations from a parent species and subsequent evolution. What is the barrier to zygote production for the Antelope squirrels (besides the Grand Canyon)? Species extinction rates are rapid at times of ecological stress (five major extinctions; human impact) 4. This example of sympatric speciation occurred through habitat differentiation: apple maggot flies began to prefer apple trees as host plants, whereas their ancestors used hawthorn trees. The shorter the time between generations the faster that speciation can occur. Concept 22.1 The biological species concept Interactive activities include drag & drop words to form a definition of a species, drawing lines to match up prezygotic barriers, creating a timeline of mass extinction events, identifying causes of extinc, This video handout was made to accompany the Speciation video made by The Amoeba Sisters and hosted on YouTube.

A mule is the hybrid offspring of a female horse and male donkey. In a normal cell division event chromosomes replicate, pair up, and then separate so that each new cell has the same number of chromosomes. wY:G`m[;#1v0s($*Bb@%zanx\cz59I;oYb U\*?e0Y>t93 oK=?f2]PIN6qbR@Jk6CO~[c`+[`%#HJJa~J!mM;M Speciation is the formation of new species through evolution. For instance, if one group evolves large body size and the other evolves small body size, the organisms may not be physically able to matea prezygotic barrierif the populations are reunited. %%EOF Some types of prezygotic barriers prevent reproduction entirely. stream The prefix auto- means self, so the term means multiple chromosomes from ones own species. For example, male fireflies use specific light patterns to attract females. 1 0 obj This is called adaptive radiation because many adaptations evolve from a single point of origin; thus, causing the species to radiate into several new ones. This scenario does play out in nature, as do others that lead to reproductive isolation. They cover allopatric and sympatric speciation, as well as prezygotic and postzygotic barriers to successful reproduction. Web1. This means that speciation occurred after just a single generation! How does geographic isolation lead to speciation? If there are more than five, the parents cannot adequately feed the young. Why would groups of organisms in a population stop interbreeding when they still live in the same place? HWn@}+oPrHMzW6>T}6641f]h"!s\\6|XZ8?Y[,r_ycmaabUB/HH The Hardy-Weinberg Principle is an essential component to a unit on the evolution of populations, population genetics, and speciation.

Darwin envisioned speciation as a branching event. 2. Identify which type of reproductive isolation is being show in each example below: G = geographic T = temporal B = behavioral _____1. Part 1: 1. Other times, populations become separated after some members cross a pre-existing barrier. Also, as a class, we review the Google Slides on the subject. These individuals would immediately be able to reproduce only with those of this new kind and not those of the ancestral species. One classic example is the North American apple maggot fly.

For example, members of a mainland population may become isolated on an island if they float over on a piece of debris. At first, this idea may seem kind of weird, especially after thinking about allopatric speciation. It has students put the steps that lead to speciation in order, analyze scenarios and apply concepts to determine the types of isolation taking place. Some species appear similar to one another. Biologists group allopatric processes into two categories: dispersal and vicariance. =======================================================, Students begin with a starter that opens the conversation for causes of evolution. Quiz & Worksheet Goals. start superscript, 6, comma, 7, end superscript, start superscript, 8, comma, 9, end superscript, There are now evidence showing that Homo sapiens interbred with Neanderthals and produced offspring. What major changes must one breed undergo in order that they become incompatible to mate to another bread? Notice how it takes two generations, or two reproductive acts, before the viable fertile hybrid results. These videos can be used in-class or as homework. The original host plant of these flies, however, was the hawthorn tree. That is, organisms are usually considered to be members of the same species if they can successfully reproduce with one another. Summarizes the 3 main methods of reproductive isolation: geographic is, Are you teaching evolution and how speciation occurs? This is called, Two species might reproduce at different times of the day or year and thus be unlikely to meet up when seeking mates.

The biological species concept connects the idea of a species to the process of evolution. WebSpeciation Worksheet Name: ____ KEY ________________ Speciation - the formation of new and distinct species in the course of evolution. ========================================================== I did not intend this activity to be a high level assignment, just practice. Scientists have discovered more than half of all plant species studied relate back to a species evolved through polyploidy. Like with all the other worksheets in the past, a template can be found at the end of this document. This type of speciation is seen in different types of organisms like bacteria, fish, apple maggot fly. WebSpeciation Worksheet. Finches with [ large / small ] beaks were most likely to survive. Notice the differences in the species beaks in Figure 3. Biologists often divide the ways that speciation can occur into two broad categories: Let's take a closer look at these forms of speciation and how they work. This is known as, Two species might have bodies or reproductive structures that simply don't fit together. Isolation of populations leading to allopatric speciation can occur in a variety of ways: a river forming a new branch, erosion forming a new valley, a group of organisms traveling to a new location without the ability to return, or seeds floating over the ocean to an island. In this locale, two types of cichlids live in the same geographic location but have come to have different morphologies that allow them to eat various food sources. Over time, those feeding on the second food source would interact more with each other than the other fish; therefore, they would breed together as well. In fact, the presence in nature of hybrids between similar species suggests that they may have descended from a single interbreeding species, and the speciation process may not yet be completed. The first page includes a prior knowledge "hook" activity and multiple choice questions that follow the sequence of the video. endobj Reproductive Barriers: Prezygotic 1. Temporal Isolation 3. Additionally, scientists have found that the further the distance between two groups that once were the same species, the more likely it is that speciation will occur.

Where do new traits come from? endobj This is a collaborative activity where students will have a population of beetles. For speciation to occur, two new populations must be formed from one original population and they must evolve in such a way that it becomes impossible for individuals from the two new populations to interbreed. Hope that helped. For example, a cricket population that was divided after a flood could no longer interact with each other. Recall that a zygote is a fertilized egg: the first cell of the development of an organism that reproduces sexually. Paper and Digital version included.This evolution through Natural Selection guided reading expository text comes with note-taking templates, comprehension worksheets that have leveled qu, Evolution of Species - Mechanisms of Isolation & Speciation Species are separated from one another by.

Because mules are sterile, they are not classified as a distinct species. Materials needed per group: Dixie cup, skittles, and a paper towel. That is, they won't exchange genes with one another even if the geographical barrier is removed. The PowerPoint is fully editable. An immigrant species bred with the local birds on the island which created a new lineage of birds, which were different from the original population.
