When Bats Took Flight

  • Bats pretty much appear in the fossil record as recognizable, full-on, flying bats. And they show up on all of the continents, except Antarctica, around the same time. So where did bats come from? And which of the many weird features that bats have, showed up first?

        Lacewings had been around since the Jurassic, and the nocturnal Green Lacewing, with its echolocation evasion system, evolved in the early Eocene (c50millon yrs ago). Something must have been hunting them. https://www.researchgate.net/publication/308952785_Cenozoic_climates_and_the_evolution_of_green_lacewings_Neuroptera_Chrysopidae

                      The answer is simple. Bats obviously developed echo-location and flight simultaneously. Aha! I be you didn't think of that! They developed it at the same time. Bats, which were previously gopher like criters, first started jumping to catch insects. They could gradually jump further and further, and hear the insects close by. And gradually the gopher like criters that could hear and glide the furthust only survived. This evenentually became powered flight AND sonar AT THE SAME TIME! I'm a genius!

                          Wait what if bat ancestors weren't nocturnal and hunted insects in the day too than they could see the insects whil gliding than as there wings developed and they got better at flying they slowly terned nocturnal to protect themselves from predators like birds? I'm not sure how plosible it is or if it makes sense, but an idea

                            I think they lived underground and developed flight to travel between burrows.

                                          Maybe the first bats weren't nocturnal, so didn't need echolocation to see prey in daylight? I'm fairly sure that no birds have echolocation...

                                              Well in French bats are called chauve souris that can be translated as bald mouse, so for me it always appeared that Bats evolved from a Tree rodent that looked like a Mouse or a Rat. Tho it would have been bonkers to have the bats related to us.

                                                      Doesn’t seem like the best science education to ask us which method we support when we have had a 10 minute introduction to the topic rather than from reading the scientific literature regarding it. I mean science doesn’t care about our opinion and just because the first explanation seemed to make the most sense to me doesn’t mean it happened that way. Especially relating to evolution where we keep figuring out that things are weird and surprising.

                                                          It does make sense that bats come from the group laurasiatheria. If u think about it and look at the bone structure of the bat and whale, they kinda look similar

                                                            and also dolphins are able to echolocation and both dolphins and whales are closely related then that explains why they are closely related.

Because they are smaller than most birds of prey and probably found it hard to compete so... they became nocturnal and developed echo location to become more efficient at hunting at night. This is my theory despite the word usage that express facts. Lol
