Los primeros homínidos abandonaron los árboles y comenzaron a caminar erguidos y sobre sus dos pies hace al menos 3,6 millones de años, tal y como confirmó un estudio difundido el viernes por la revista PLoS ONE. Según científicos de tres universidades estadounidenses, se creía que hasta entonces esos homínidos no eran bípedos y que pasaban la mayor parte de su vida en los árboles. A finales de la década de 1960 un grupo de científicos descubrió en Laetoli, Tanzania, marcas de pisadas de homínidos preservadas en cenizas volcánicas desde hacía unos 3,6 millones de años. Las marcas de esas pisadas habrían sido dejadas por miembros del grupo homínido Australopithecus afarensis. Esa especie incluye a 'Lucy', cuyo esqueleto fosilizado es el más completo de un Australopithecus encontrado hasta ahora.

Which two strategies helped the amphibious invasion force be successful?​
kramer

The two strategies are Arrange the beaches for the Allied soldiers and ways to stop the withdrawal in Germany

<u>Explanation: </u>

The impact of D-Day echoes in history:

  • It's the biggest military attack ever. The German forces encountered cold weather as they assaulted the coast of Normandy with raging German fire. The Allies won the war, despite the difficult odds and high losses, and turned the tide of World War II towards victory over Hitler.
  • On D-Day, the strategy was to clear the beaches for entries of the allies by heavily attacking Nazi weapons on the coast and damaging the major bridges and roads to shut down the withdrawal and strengthening’s of Germany. In order to protect the coastal areas before the military invasion the parachutists would then fall down.

Nevertheless, almost none went according to plan.
