How do scientists know how different species are related? by Emily Reece https://padlet.com/emilyreece48/m0zk57r4yx39 en-us 2017-03-20 01:34:03 UTC 2023-01-25 05:34:58 UTC hello@padlet.com Anatomical Evidence of Relationships: emilyreece48 https://padlet.com/emilyreece48/m0zk57r4yx39/wish/161052123  Anatomy is the study of the structure of an organism.
 Fossils are excellent evidence used to determine relationships between the past and present. Organisms may look different from the outside, but may have similar structures inside. ]]> 2017-03-20 01:54:46 UTC https://padlet.com/emilyreece48/m0zk57r4yx39/wish/161052123 Physiological Evidence of Relationships: emilyreece48 https://padlet.com/emilyreece48/m0zk57r4yx39/wish/161052281  Physiology is the study of the functioning of organisms. Physiology includes the study of the biochemistry of an organism. Comparing proteins among different species, allows one to measure the degree of similarity or difference in their genetic make up. Proteins are coded for by the organism’s DNA. ]]> 2017-03-20 01:56:34 UTC https://padlet.com/emilyreece48/m0zk57r4yx39/wish/161052281 DNA Evidence of Relationships: emilyreece48 https://padlet.com/emilyreece48/m0zk57r4yx39/wish/161052338  Genes are sections of DNA made of long chains of molecules of nucleotides. Technological advances have made it increasingly possible to determine the sequence of nucleotides of a specific gene. New DNA evidence has meant that prior classifications based on morphological, physiological, or other evidence, must be restructured. ]]> 2017-03-20 01:57:10 UTC https://padlet.com/emilyreece48/m0zk57r4yx39/wish/161052338 Phylogenetic Trees: emilyreece48 https://padlet.com/emilyreece48/m0zk57r4yx39/wish/161052477  Phylogenetic Trees are used to represent a hypothesis about the evolutionary relationships among groups of organisms. Like a family tree, the roots or the base of the phylogenetic tree represents the oldest ancestral species. The upper ends of the branches represent the present day species. Forks in each branch represents the points in the past at which an ancestral species split-evolved, or changed over time, becoming two new species. ]]> 2017-03-20 01:58:42 UTC https://padlet.com/emilyreece48/m0zk57r4yx39/wish/161052477 emilyreece48 https://padlet.com/emilyreece48/m0zk57r4yx39/wish/161052706 2017-03-20 02:00:37 UTC https://padlet.com/emilyreece48/m0zk57r4yx39/wish/161052706 Sources: emilyreece48 https://padlet.com/emilyreece48/m0zk57r4yx39/wish/161052901 http://www.dpcdsb.org/NR/rdonlyres/88CE505C-31BC-4DDC-88C2-FEBBEA20ADD3/118582/Notes12HowareSpeciesRelated.pdf]]> 2017-03-20 02:03:21 UTC https://padlet.com/emilyreece48/m0zk57r4yx39/wish/161052901 https://padlet.com/emilyreece48/m0zk57r4yx39/wish/196286990 2017-10-12 06:01:00 UTC https://padlet.com/emilyreece48/m0zk57r4yx39/wish/196286990 https://padlet.com/emilyreece48/m0zk57r4yx39/wish/266681462 2018-06-11 19:08:05 UTC https://padlet.com/emilyreece48/m0zk57r4yx39/wish/266681462 Omg https://padlet.com/emilyreece48/m0zk57r4yx39/wish/523270813 2020-04-22 15:01:27 UTC https://padlet.com/emilyreece48/m0zk57r4yx39/wish/523270813
