- Animals are always becoming stronger and better suited.
- Since our environment is always changing, we develop to adapt to that environment. 
- Fossils play a massive part in evolution, we look at old fossils and it indicates how we have changed so much. We can contrast and compare the differences.

- Environmental pressures caused different adaptations.
- EVOLUTION!!
- Different appetites.
- Different prey and predators available.
- They come from different habitats and environments.

OR the gradual development of something.
Extinction: The state or process of being or becoming extinct/dying out.
Fossil: The remains or impression of a prehistoric plant or animal embedded into rock and preserved in a petrified form. OR the preserved evidence in rocks or soils of organisms that were once alive.
Organism: An individual animal, plant, or single-celled life form.
Species: A group of similar individuals that interbreed only among themselves to produce fertile offspring under natural conditions.
Asexual Reproduction: The type of reproduction by which offspring arise from a single organism and inherit the genes of that one parent only and does not involve the fusion of gametes.
Sexual Reproduction: The production of new living organisms by combining genetic information from two individuals of different types. This includes a gamete produced by both male and female individuals. ]]> 2018-10-11 01:30:40 UTC https://padlet.com/shenaemcguinniss/ja2etmzwjp0t/wish/291526915 11th OCTOBER: shenaemcguinniss https://padlet.com/shenaemcguinniss/ja2etmzwjp0t/wish/291529875 ARTICLE + QUESTIONS ]]> 2018-10-11 01:47:20 UTC https://padlet.com/shenaemcguinniss/ja2etmzwjp0t/wish/291529875 WHY DO MEN EXIST ARTICLE: shenaemcguinniss https://padlet.com/shenaemcguinniss/ja2etmzwjp0t/wish/291530435 2018-10-11 01:50:14 UTC https://padlet.com/shenaemcguinniss/ja2etmzwjp0t/wish/291530435 What is the advantage to a species when very large numbers of offspring are produced? shenaemcguinniss https://padlet.com/shenaemcguinniss/ja2etmzwjp0t/wish/291530776 When a large number of species is produced in a community, the advantages are very beneficial. The main advantage is the species will not become extinct and have a high and healthy population growth.  ]]> 2018-10-11 01:52:19 UTC https://padlet.com/shenaemcguinniss/ja2etmzwjp0t/wish/291530776 What disadvantage of sexual reproduction was cited by one of the scientists? shenaemcguinniss https://padlet.com/shenaemcguinniss/ja2etmzwjp0t/wish/291530908 Sexual Reproduction is the product of living things combining their gametes to produce offspring. The only disadvantage to this process explained in the article is that only half of the offspring produced from sex (the daughters) will produce offspring themselves. There argument was that why would any species then waste their time and effort on producing sons?]]> 2018-10-11 01:53:03 UTC https://padlet.com/shenaemcguinniss/ja2etmzwjp0t/wish/291530908 In paragraph 1 the term evolutionary selection is used. Try to explain what this means. shenaemcguinniss https://padlet.com/shenaemcguinniss/ja2etmzwjp0t/wish/291531045 The term evolutionary in paragraph 1 is referring to the process of evolution which is the belief that different kinds of living organisms have developed from one another and earlier during the history of Earth.

The advantages cited in the article include: healthy competition between males for the females attention, and improves overall the genetic health of populations. It does this by acting as a filter to remove harmful genetic mutations, helping populations to flourish and kill extinction in the long term. Sexual societies also are more resilient to extinction in the face of inbreeding.]]> 2018-10-14 02:30:42 UTC https://padlet.com/shenaemcguinniss/ja2etmzwjp0t/wish/292481194 Explain what is meant by sexual selection? shenaemcguinniss https://padlet.com/shenaemcguinniss/ja2etmzwjp0t/wish/292481470 In the article, multiple times sexual selection is referred to. Sexual selection is similar to sexual reproduction. Scientists use this term to explain the nature of sexual reproduction. The sex and overarching domination in a society of sexual reproduction is selected by there breeding process: sexual reproduction. Overall, they are using this term to show how sexual reproduction is a selective agent. ]]> 2018-10-14 02:36:31 UTC https://padlet.com/shenaemcguinniss/ja2etmzwjp0t/wish/292481470 Does the evidence cited suggest there is more benefit to a species to reproduce asexually or sexually? Use information in the article to defend your answer. shenaemcguinniss https://padlet.com/shenaemcguinniss/ja2etmzwjp0t/wish/292481591 The article shows both sides of a sexual and asexual species. Overall, the evidence in the article suggests there is more benefit to a sexual society as it specifically states "An absence of selection — when there is no sex or no need to compete for it — leaves populations weaker genetically, making them more vulnerable to dying out." Following this statement, the article begins to outline the advantages to reproducing sexually: competition between males and genetically stronger organisms. This reinforces how reproducing sexually adds many benefits to a society. ]]> 2018-10-14 02:39:03 UTC https://padlet.com/shenaemcguinniss/ja2etmzwjp0t/wish/292481591 17th OCTOBER: shenaemcguinniss https://padlet.com/shenaemcguinniss/ja2etmzwjp0t/wish/293706828 New Class 2.1 Questions]]> 2018-10-17 07:05:18 UTC https://padlet.com/shenaemcguinniss/ja2etmzwjp0t/wish/293706828 1.

Discuss your point of view. shenaemcguinniss https://padlet.com/shenaemcguinniss/ja2etmzwjp0t/wish/294151883 In my opinion, I believe genetic technology should not be brought onto extinct species as evolution is a way of life that is done for a reason.
