With whales, the larger ones each plankton, the medium sized ones feed on plankton and the smaller ones dine on fish. Their body features such as snout length can fluctuate within the still interbreeding members f the whale kind.  ]]> 2017-06-14 04:32:11 UTC https://padlet.com/gabrielle_mcfarlin/fi2ml4d44ktu/wish/176348513 gabrielle_mcfarlin https://padlet.com/gabrielle_mcfarlin/fi2ml4d44ktu/wish/176349463 In some whale species the behavior of them may be affecting the course of genetic evolution.

Natural selection can cause small changes such as population size or color over times. But it can also completely change a species. Random genetic changes caused one whale to have its nostrils back further than usual. Which caused later generations to have nostrils back further on the head. As shown in the image below.]]> 2017-06-14 04:54:51 UTC https://padlet.com/gabrielle_mcfarlin/fi2ml4d44ktu/wish/176350263 gabrielle_mcfarlin https://padlet.com/gabrielle_mcfarlin/fi2ml4d44ktu/wish/176355573 2017-06-14 06:29:25 UTC https://padlet.com/gabrielle_mcfarlin/fi2ml4d44ktu/wish/176355573 gabrielle_mcfarlin https://padlet.com/gabrielle_mcfarlin/fi2ml4d44ktu/wish/176355860 2017-06-14 06:32:23 UTC https://padlet.com/gabrielle_mcfarlin/fi2ml4d44ktu/wish/176355860 gabrielle_mcfarlin https://padlet.com/gabrielle_mcfarlin/fi2ml4d44ktu/wish/176356104 2017-06-14 06:35:27 UTC https://padlet.com/gabrielle_mcfarlin/fi2ml4d44ktu/wish/176356104 gabrielle_mcfarlin https://padlet.com/gabrielle_mcfarlin/fi2ml4d44ktu/wish/176356332 Scientists have found that a genetic mutation in the eyes of right whales that interfered with their ability to see in bright light may make them more susceptible to fatal knots in fishing gear, one of the major causes of death for this critically endangered mammal.]]> 2017-06-14 06:38:20 UTC https://padlet.com/gabrielle_mcfarlin/fi2ml4d44ktu/wish/176356332 gabrielle_mcfarlin https://padlet.com/gabrielle_mcfarlin/fi2ml4d44ktu/wish/176357526 Whales migrate to eat and breed mostly. Whales cannot gibe birth in colder temperatures of water so they travel to warmer waters, Where as the other whales migrate seasonally. ]]> 2017-06-14 06:53:27 UTC https://padlet.com/gabrielle_mcfarlin/fi2ml4d44ktu/wish/176357526 gabrielle_mcfarlin https://padlet.com/gabrielle_mcfarlin/fi2ml4d44ktu/wish/176357605 2017-06-14 06:54:19 UTC https://padlet.com/gabrielle_mcfarlin/fi2ml4d44ktu/wish/176357605 gabrielle_mcfarlin https://padlet.com/gabrielle_mcfarlin/fi2ml4d44ktu/wish/176358215 2017-06-14 07:01:47 UTC https://padlet.com/gabrielle_mcfarlin/fi2ml4d44ktu/wish/176358215
