31. Lamarck ( 1809 1959 ) gave clade the general meaning of any monophyletic branch of the evolutionary tree . 32. Since its discovery, the 145-million-year-old Archaeopteryx has perched alone on a low branch of the avian evolutionary tree . 33. In 2009, Warnow and her colleagues released their SAT?software for co-estimating biological multiple sequence alignments and evolutionary trees . 34. Only later did the forerunners of today's eukaryotes split off from the more ancient parts of the evolutionary tree . 35. Farrell constructed an evolutionary tree including more than 100 species representing the many kinds of beetles that eat plants. 36. Statistical techniques such as jackknifing help in providing reliability estimates for the positions of haplotypes within the evolutionary trees . 37. Certain excavates are often considered among the most primitive eukaryotes, based partly on their placement in many evolutionary trees . 38. According to this evolutionary tree , chimps and bonobos were first to branch off the trunk leading to modern people. 39. Could there have been a jump ( punctuated evolution ) in the very early part of the evolutionary tree ? 40. Remarkably, scientists are finding their genes to be ancient, putting them among the deepest roots of the evolutionary tree .
