Interaction between evolution and time machines

Several years ago I speculated about interplay between evolution and time machines. What happens in a world in which both evolution and time machines play significant roles?

So far, the only piece I saw which attempts to address this issue, is the one which I wrote at https://www.zak.co.il/ideas/stuff/opinions/eng/evol_tm.html

פעולת גומלין בין אבולוציה ומכונות זמן
לפני שנים רבות העליתי השערות על פעולת הגומלין בין אבולוציה ומכונות זמן. מה קורה בעולם, שבהתפתחותו לקחו חלק נכבד גם אבולוציה וגם מכונות זמן?
עד כה, המקום היחידי שראיתי, ושמנסה להתמודד עם הנושא, הוא שבו כתבתי ב: https://www.zak.co.il/ideas/stuff/opinions/eng/evol_tm.html

I am deaf since birth. I played with big computers which eat punched cards and spew out printouts since age 12. Ever since they became available, I work and play with desktop size computers which eat keyboard keypresses and spew out display pixels. Among other things, I developed software which helped the deaf in Israel use the telephone network, by means of home computers equipped with modems. Several years later, I developed Hebrew localizations for some cellular phones, which helped the deaf in Israel utilize the cellular phone networks. I am interested in entrepreneurship, Science Fiction and making the world more accessible to people with disabilities.
