Mbiri isanayambe derali - Mbuye wa dziko lonse lapansi!

Evolution - chinthu chowopsya. Nthaŵi iliyonse siteji ya mapangidwe lathuli mu nyengo zina za nthawi padali nyama, ndithudi, ndi osankhika nthawi yake. Anthu kale ndi ogwirira mbiri isanayambe. Za iwo ndi kukayankhula.

nyama peresenti padziko Lapansi zoposa 500 miliyoni zaka! Pafupifupi theka la nthawi ino, dziko kunalamulidwa ndi ogwirira mbiri isanayambe - zinyamazi! Inu tangoganizani za manambala amenewo! Palibe gulu la ziweto sakanakhoza kupulumuka mu mbiri ya mapangidwe a Dziko Lapansi kwa bola chinachitika mu zinyamazi wakale. Iwo anali ogwirizana kwambiri

Mbiri isanayambe derali - korona wa chilengedwe cha uthunthu!

Pa nthawi ina, ndi zokwawa wakale ndi chimake cha chitukuko cha zamoyo zonse lapadziko zokhala lathuli. Zinyamazi anali mafumu a dziko zaka 100 miliyoni! Iwo anali ochuluka ndi osiyanasiyana mizukwa. Palibe cholengedwa ena sakugwirizana nawo mphamvu ndi ungwiro! Today ogwirira mbiri isanayambe, zokwawa sasiya zikuvutitsa maganizo asayansi ndi umbuli: ndondomeko ya moyo wawo ndi kutha kwa sewero kuimira chidwi cha munthu kuchokera nthawi anaphunzira wa Age Great zapoizoni! Zinyamazi anaphunzira mosamala kwambiri, palibe mtundu wa nyama zinatha sindigwiritsa ntchito mu asayansi monga wotchuka kwambiri kuposa zokwawa wakale!

Mbiri isanayambe ogwirira m'madzi

M'kupita kwa nthawi, dziko linali yachuluka, ndi ena zokwawa anayamba kufufuza madzi. Asayansi kunachokera experimentally kuti zokwawa m'mbiri yonse ya chitukuko, nthawi kumbuyo kwa madzi. Izi zinachitika pamene iwo anali kuyembekezera chakudya, n'zodalirika chitetezo wochuluka. Pakuti iwo ndi palibe vuto, chifukwa moyo m'nyanja ndi m'nyanja amafuna kuchokera zokwawa alibiretu rearrangements zikuluzikulu za thupi ndi Maphunziro Akakhalidwe Kazolengedwa.

Oyambirira ogwirira mbiri isanayambe, katswiri madzi, anali anapsid - Mesosaur Permian. Kumbuyo madzi anasiya wosazindikira Diapsid - tangozavry, talattozavry, ndi klaudiozavry hovazavrusy. Gulu zaposachedwapa zapoizoni m'madzi ichthyosauri kukhala chidwi. ogwirira izi m'madzi ankangomumwaza chapamwamba ndinazolowera moyo mu madzi iliyonse ya dzikoli. Mu ichthyosaurs mawonekedwe kwambiri ngati nsomba ambiri kapena anamgumiwa: triangular mutu ndi pakamwa yaitali, wotambasula thupi, flattened m'mbali, tsamba mchira chipsyepsye - ndi ofukula ndi miyendo lidzasinthidwa anayi ventral chipsyepsye.

Ambuye mwa nyanja ndipo nyanja Yaikulu wamoyo mu chokwawa madzi anali liopleurodon wina. ena onse m'madzi mbiri isanayambe ogwirira chabe chinazilala pamaso pake ... moyo wake wa utagwa kwa nthawi Jurassic. Za kukula kwa zolengedwa ichi chachikulu nkuyendabe mtsutso maphunziro. Zinayi zikuluzikulu zipsepse lalifupi ndi laterally wothinikizidwa mchira, komanso lalikulu kwambiri ndi yopapatiza mutu ndi mano akulu (za 30 cm m'litali) anamuika wolamulira yamphamvu mwa nyanja onse ndi nyanja ya dziko wakale!
